When purchasing a used outboard.................

[Blue_Runner]

Flounder, first off my 150hp Yamaha probably has well over 300 hours and she's just getting started!

I don't have an hour meter so that's just an estimation. Another friend of mine has an hour metere and he bought his motor at the same time as I bought mine. I run mine more than he does and he has over 200 hours so that's where I get my estimation.

I'd say compression is the first thing to check for sure. Of course there are many many factors involved here - does it look like it was taken care of? Does the owner sound knowledgeable about maintenance issues such as impeller, fuel filters etc. Also I know others will agree that you should sea-trial if possible. Know the manufacturers suggested max RPM's beforehand and pitch of prop in order to see if the motor is making max RPMs at WOT.

You'll know when you find a good one. The sun, moon and stars will allign....you'll hear violins and trumpets in the distance....bikini clad women will dance in your thoughts....ok well maybe not that last one but you get the picture!

Good luck man!
