Well, before you go too far finding a mechanic… There are a few things to know about the 75hp models. They were meant for high speed/lightweight boat applications and oftentimes don’t perform well on conventional runabouts. These engines lack much of the mid range power needed to help get a boat on plane. Especially if the boat is relatively short, with a deep V and tends to “squat” on acceleration. Once on plane, does it seem like the engine is making full power?
You may want to start with a reliable tachometer. Do you know what RPM the engine turns up at WOT? I am assuming the engine does not have power trim and tilt. Do you know what pitch prop you are using, or perhaps the part number of the propeller? These engines really need to spin up their maximum RPM (5500) in order to deliver any power. Have you done a compression test? These engines had higher compression than their 70hp counterparts, so lugging them at low WOT RPM coupled with today’s low octane fuels tends to wear them out prematurely.
I used to be the service rep for your area many years ago. I’m pretty sure both of these shops still exist, Knapiks in Amsterdam is a good repair shop for older engines. Nick Roberti’s Marine in Kingston is also a good place for older engines. It won’t be cheap, but they will be honest with you and are familiar with your engine. Please tell them that Don Kellogg recommended their shops for you.
