hi all, i have a customer who has a blown powerhead on his 25hp yamaha and he would like to put a larger motor on the back. is there a larger HP powerhead that will fit in the 25P case & have the lower end hold up? he was talking about going to 50HP, i told him that big of a jump would require a whole new unit. im correct in that auuumption, right?

next question, what can i get away with if we change out the whole unit? do i need new controls ? if i do not stay with Yamaha, will any make o/d mount up to the exiting power tilt, wiring and controls?
as always, thanks for the help, these forums are a lifesaver
 
He,s more than likely right if you study the drawings you will see that the oil pan gasket , the drive shart fit also some 30hp ,40 ,50 hp i just glimps over and never studyied it to detail . who knows unless you try.
