TD42T. Enough power, easy to marinize, no mucking about with computers, cheap to buy and source parts, reliabilty plus.
I feel dirty for saying it, but I drove a turbo diesel focus the other day and it was so so nice to drive. Real wedge of torque from idle, and hauled arse after that.. Trim off all the Ford-ness plastic crap and you're left with something useful
Yeah, the wee diesels are pretty good. Trouble is the road user charges kill the cost advantages. Doing the maths my Bighorn is $26/100km and the Forrester is only $18 not taking into account servicing. With a boat, where you don't have to pay the road user charges, there would probably be an advantage. With the amount of use it will likely get that advantage won't be much, if anything, with servicing costs. So I think I'll stick with petrol for the boat.
1UZFE?
Probably a bit too much engine. Like the idea though.
A straight 6 is probably good for space, long and narrow so easy to get down the sides in a small tub. Unfortunately with the trend for FWD cars to maximise cabin space they are not suitable for cars so pretty scarce. There will be a few straight 6 commercials but they will be heavy. I think a V6 is probably going to be the best option.
A 1UZ is pretty compact and light for what it is. The Beamer mention above was cast iron block and alloy head if I remember correctly, and the 1U was 2 cylinders shorter and 20kg lighter, with double the power and torque. There's a shit load avail off the shelf for turning the humble Lexus into a boat motor too.
What rpm motor is the gearbox and leg designed for?
Leyland P76 may be worth considering. Cheap to buy already marinised from the jet boat crowd, develops good HP, lightweight at about 150kg plus accessories.
Was going to suggest a manual pumped qd32
Late model Honda stuff turns the right way but you would need aftermarket ecu
To get away from electronic throttles and other shit you don’t need
Front runners look like the V6's, Buick 3.8, VQ30DE or VQ25DE. Most of the straight 6's seem to be from RWD vehicles that get thrashed by the wheel spinners. Buick would be best match speed wise but the Nissan's are within coeey.
how is it cooled? if no heat exchanger I would stay away from alloy if used in salt water.
The current engine is raw water cooled. That with the fact it is about 45 years old and hard to get parts for makes me keen to do a swap. The replacement set up will have a heat exchanger added so that fresh water will continue to be used in the engine. Word is, from a US marine engine site, that it is not a good idea to add a heat exchanger to the old engine as the fresh water with anti freeze/boil will tend to find where the engine is corroded and eat out what is left.
I agree, anti freeze finds any leak
The Ford Bara engine might be worth a look as well. If you go aftermarket efi there is a surprisingly small number of sensors that you need to run an engine, in fact the megasquirt (and probably most others) can make an engine run with just the engine speed and manifold pressure sensors...
My Range Rover is running with;
Crank speed/position sensor
MAP sensor
Air intake temp
Coolant temp
Throttle position
and sometimes a wideband O2 sensor
The only outputs are
4 ignition outputs (wasted spark)
2 banks of injectors
idle speed valve
fuel pump relay
They are really pretty simple when you strip away what isnt needed, a later engine with variable cam timing will need a cam position sensor as well
