" it has lasted a long time so I am happy with the boat, and the performance is stunning."
If that's the case Robert why risk burning her up with "a more beefy motor"?
Basic question is - Why does she need a new motor in the first place?
(Test/development engineer in me coming out again!🙄)
What's wrong with the original motor?
And would an identical replacement go the same way?
First find the cause and then consider the way forward!😉
Cheers, Doug 😎
PS: Some pics and dimensions of the boat would be helpful 👍
