Thread: Ali boat repairs needed waikato

not too helpful but nautech marine near river head auckland was excellent. Awesome value for money and the welds are great

Managed to remove the floor boards today and there was a lot of small foam looking spots,touching them they would wipe away with a slight gritty feel to them,father in law who is a sparky and does a lot of boating reakoned disconnecting the battery would help.couldn’t find any onnodes on the outboard to speak of .

so fryan dingy has warning label on it not to use steel fittings etc etc etc to stop reaction (galvanic??) its electrolisis or fancy name for rust of non iron type metals...if you put a say 4" nail on bottom of alloy boat,the reaction between the two metals can see the nail eat its way through hull

which begs question has your boat been in salty near Kawhia and picked up iron sand.....
would this be enough to cause issues????
MS2 will gum up holes short term but if hull is that far gone....would you trust it???
had this issue with fryan we bought...fortunately we spotted issue straight away and Mr Boats was good enough to take it back for full refund with apolagy,we privately bought another and have kept it out of salt water and are reasonably careful to keep it clean and free of metal stuff.

Fish raglan a fair bit and have used her a lot on lake tarawera,might be the acidity in the lake water now I think about it.the old girl is still solid otherwise.

Get a battery isolation switch if it hasn't and isolate anytime it is not in use.

If you pull up all the floor and floatation and give it a good high pressure water blast all that chalky oxide will piss off and you can see what you are dealing with.....I would use salt away over the whole bildge and floatation too.

Fryans (and others ) that use foam blocks under a non sealed floor suffer this fate usually because salt gets between the hull and close fitting foam and doesn't dry out.....just sitts there fizzing in your garage or yard.
Some people take it out and throw away (not reccommemnded) some people replace with lots of plastic bottles...or the best one I have seen fill up the cavities with those balls used in kids play things.
Im still running the factory foam under my floor but am diligent with salt away/ getting it dry and pulling it up once a year to clean and salt away everything.

Also check that absolutely none of your electrics are using the boat as an earth.

Took the flotation out years ago,have an isolated switch fitted,will hit the father in law up about the earth thing,not a lot of electrics on the boat,bilge pump,old as fish finder,hydraulic tilt and nav lights are about it I think.
