What caliber........... boat.

Seeing all the fun and adventures you fullas are having with boats, I’m asking some noob questions.
Growing up there was a boat in the garage and we used to get together with others and have a heap of fun ourselves, fishing and waterskiing.
Wondering what the pros and cons are for each.

My thoughts......
I’m thinking a jet would be good, but will probably hardly ever get it in a river, so outboard would be more logical.
I thought a jet could be cheaper motor servicing than an outboard, due to it just being a car motor, so any back yard mechanic should be able to work on it.
What are the approx service costs for a outboard vs jet.

Ongoing running costs...
Jet boats have impellers, wear rings ...... How long do they last, expected life, and what other consumables.
Do outboards have lower day to day running costs.
Fuel use? Only looking at a smaller engine/motor, but which would use more fuel?
It wouldn't get out much, occassional fishing trips and towing a skier, kids in biscuit etc
I hate what sea water does to machinery, so will be fresh water only

Not looking at spending a fortune, so it will have been someone else's which has been rolled, bowled and arseholed, so what else should I be looking for. I've heard older fiberglass can get rotten or something, so what's that about
I know I'm trying to compare 270 with 7mm08, but some of you may have had both and got some answers.
Cheers

In my experience I use a jetboat more but probably due to where I live and play.

My mclay with a 4 stroke has cost me nothing since I bought it but a service which I got done for cheap by an ex merc mechanic working at the local garage.

It is very cheap to run so far. (4stroke)
I use it in both salt and clear and there are no issues if you look after them and run them in fresh as soon as possible.
I just back mine down to the river in front of home and wash it down and run the motor.
I reckon a good outboard is lower maintenance and cheaper in the longrun.

So what you should be hearing is the 708 option just makes a lot more sense and is a lot more useful.overall against the 270 ...:thumbsup:

for what its worth we have a plain jane 13' tinny and now have a 15hp 2stroke on it....it will do 39kmph with 2 adults and 2 dogs so should comfortably drag a bickie along if you werent trying to be a hoon and tip someone out...it will take care of any lake fishing we ever want to do and if its to rough or choppy for it we shouldnt be out on water. we have caught loads of fish from it and it owes us nothing...I believe now we have a 15 I possibly COULD use 20ltrs of fuel in a weekend but it would be a big one.... you stick say a 140hp on back of a boat and you will use that in a couple of hours if you lucky. horses for courses...work out what you really want to do and go backwards from there.

Should be able to like own posts...

I like boats oraki, it's just I find they are best if they are someone else's.
I know, not helpful , sorry.:)

That’s correct, but you got confuzzelled with your wit. ;) so I had to correct it
I’ve had nothing to do with jet boats as such. Just an outsider looking in and asking a few questions from the ‘wise’??????

Yip, I’ve been told the cheapest one is your mates one, just throw him fuel money and abit of sweat cleaning up afterwards.
Trouble with shift work is Ive no mates..... well they’re working when I’m off

If you seen me drive one you would workout I am anything but wise[emoji16]

Haven't seen him for a while on here but @Gerald is a sharp boatie with both jet boat and outboard.

I hava 5.2 pontoon with 90 Yamaha 2 stroke. Service is pretty basic o them they are pretty simple engines. Mine hasnt cost me anything significant other than when ove wanted to do upgrades. Using it in the salt a lot means the trailer does take a hiding and that seems to be where my biggest bills are likely to come from

Back in the day my uncle had a 135 Chrysler pushing 16-18ft boat along at 55ish mph. Not fun falling off on the outside corner when skiing...think bounce, bounce, dive, pop up gasping and ski comes along and snots you on the swede type fun
We had a Sea Nymph 16ish with a 70or80 Johnson
Other uncle had a fireball with a 50 on it.
Used to fill up all the tanks onboard, and also a 44 gallon drum. Lasted 3 days. Fuel was cheap then.
Looking around the 50- 70 size on 3.6ish metre boat. Something small enough to have cheapish fun with the kids, but big enough for when the lake cuts up to make land

Fixed it for you.....

I have a 6.2 HT, with a 150HP 4 stroke merc.
Cruise at 22 knots, and use 20-22 litres per hour.

Never been used in fresh water, and prob won't ever (apart from bar crossings).

A service is $400 ish and at 100 hours.

Cheers that’s not to outlandish. I had no idea but just thought that being a specialised type motor, you pay through the nose. I could of course take the next step and ask a service man.

After reading your thread, it got me thinking about a boat......so it's your fault I'm having the thoughts I am ;)

Using a New 140 Suzuki 4 Stroke on a Figlass Viscount
Viscount ex inboard and alloy podded for Outboard
Had a 200 E-Tech for 1st 11 years - corrosion eventually ate it (my boat is 365 days on swing mooring in salt water)
E-Tech was amazing power - 60mph and still not WOT - would start to keel waltz at about that speed)

E-Tech 200 HO

4500-5000 rpm
Fuel usage - 38-48 LPH
30-40 knts
8 mins to town (I live 9ks out from Havelock Marina)

Suzuki 140 4-Stroke

3950-4250 rpm (still running in at under 25 hours)
19-21 knts
Fuel usage 12.5 - 16 LPH
4400-4550 (were I will prob eventually cruise at) is 16-18 LPH
22-25knts
15 mins to town (I live 9ks out from Havelock Marina)
13 mins once run in

All above is with clean bum - slightest build up of foul and the fuel usage goes up

E-Tech oil cost will prob counter the extra cost od 4 Stoke service.

Driving the boat now with the Suzuki is like going from a Ferrari to Nanna's Mazda 323 :-(
But the few fish we get not taste better due to cost per Kg :-)

I prefer Fiberglass over Alloy - but less practical - but much nicer ride
You can set up a 6m Hard Top boat with new motor - hydraulic steer - braked trailer for under 40K
Alloy hull alone, will start at 40K

@Sarvo interested in what boats you mean for this price.

My boat for example - as described above

Yeah have a look around and jump on a few. Mine has no seats, room.for chilly vom, cray pots etc, five bottles etc. If your are on board you aren't there to be sitting around lol

Ive got a 566 Sea Nymph, all 1997, bought in 2000, just did the head gaskets last year on the 130HP V4 2 stroke Johnson, nice boat, I dont look at boats anymore as really satisfied with this one.
Cheap to run for size. Needs occasional battery and their achille's heel seems to be the oil injection/fuel pump, $800 replacement done once, due again, will disconnect oil pump and pre mix.
Great ski and fishing boat.
Go for HP and probably 4 stroke out board if you can, figure what hull design you need for the use your gonna give it, mine is a wide boat, plenty of room and stable to fish of with a few others

We have the peasure of using a Stabi 409 ...very solid boat ,but rides terribly in short chop! Getting to my point most boat packages are sold with just enough power to get keep the deal done keeping the price down and get the boatie fishing ..problem is if you load the said package with four solid guys / dive gear and run home into sloppy sea you burn fuel somthing terrible. We have a 60 yam doing the devils work getting us about , but will replace it as soon as funds family etc agree with a 100 Hp which will give us more for less ..more grunt for less fuel on the bad days and a better cruising speed for the sme or less fuel on the good days ...working a small engine hard will end in tears

Of a boat is rated for 90 to 135HP, ask if you can fit a 150.
Just because you have the horse's, doesn't mean you have to use them - but when you need them, generally, you'll be happy(and quite often safer) you have them.

And all of stingrays comments to :)

Yep whatever you get make sure it is well powered, which for older boats usually means at or near the max rated power.
My Fryan 450 (4.5m) with a 40hp Johnson is under powered as are most boats in that 4.2-5m range with a 40hp, with no gear at all and 2 adults its ok just but any weather and all the essential gear it is working too hard which isnt really a problem for the engine as they are designed to be run at full throttle but boy do they get inefficient at high load, 2 strokes outboards are jetted rich at high throttle openings to keep piston temps down and oil up and this results in high fuel use.

^^^Stingrays 5m stabi with 60hp fourstroke vs my 4.5m and 40hp twostroke on the same trip and one less set of dive gear and two less tanks mine with 50% less horsepower burnt 50% MORE fuel pushing a SMALLER boat just because it was working its arse off and just below full throttle to be on the plane.
A 5.5m with a 90 or 115 on it would do the trip easily in less time at a higher cruise speed and use less fuel.

A well powered two stoke vs fourstroke will burn very similar fuel at cruise, where the fourstroke uses a lot less is at high and low load so trolling speeds and repetitively accelerating up on the plane towing a skier or just goin fast for fun.

A 60hp on mine would make it a bloody good little boat, more economical and some speed to run home before the weather.

Think about what size boat will suit you best.

4.2-4.5m really only good for 2 adults unless VERY well powered and used only for ski boat (Ie glassy conditions)

5-6m and getting up to four persons comfortably but once again will want to be powered near top of spec as a ski boat.

My little 4.5m suits me well as it is easy to tow and launch by myself and with a 2wd and it fits in my garage....I would like a 5m just for the extra seakeeping ability and still just in the fits in the shed/easy to launch/tow etc range.

Its horses for courses.
