A decent looking lower unit for you in this box of goodies. You may even be able to swap the relevant parts over to convert yours to a 90.

I'm not sure that would protect rubber seals. They're a bit more temp sensitive than aluminum.

yep that's the same stuff. I guarantee you it will repair your anti-ventilation plate a treat and with minimum fuss. If you get cracking you could have the hole jon done in 4 huurs including 10 minutes of standing back and saying wow what a good job I just done. Fill the holes for the doel fins so you are not tempted to put them back on.

Yes it's good stuff - have used if for loads of things - from fixing the bog to filling break through cavities on a skimmed cylinder head.

Thanks all for the advice re this. I fitted a tilt pin, which has stopped me trimming too low, and that seems to have cured the tilt issue, obviously the hydrofoils are off so that may have done it anyway.

Filled the hole with quicksteel, at which point it looked like this:

O and I've changed the prop and painted the skeg as well.

So all in all very happy, lets see if I can knock the lot out on the way to the IOM

Hopefully all this will be useful in the event some other poor soul has the same problem. Got to say that stuff is excellent.

Yes good job... I did the same as IBWET, sorry his friend, and also did the chemical metal repair. That was 5 or 6 years ago and it still looks fine.
