Hi I know little about outboards,mercs,and nothing about Yamahas.
I am considering buying a boat that has a 75HP yamaha on it.
It is 3cyl,compression is 6bar I'm told,no idea what that is in psi,but a little low I think,but I am going to check it on Monday.What psi should I be looking for to make it a "I'll consider it".I'll also be checking for spark as it has been laid up for three years.
I looked for the number but cannot see it,I have looked either side of the transom bracket haven't had a chance to really look under the hood yet,is there anywhere on the powerhead I may find the #.
At a guess I think it may be about '80-'85,but I'll trawl the web over the weekend to see if I can find anything that looks like it.
All advice and suggestions greatly appreciated.Thank you.
