Arco Starter Rotation
I purchased an Arco Permanent Magnet Gear Reduction Starter, Part No. 70200.
A bit confused with the engine rotation/starter rotation concept so I wanted to see if someone could confirm if the model will fit my boat, before I install it tomorrow. After reading a previous post from someone who installed the incorrect rotation starter, I thought I'd better check. My engine is an '88 Ford 351, Indmar, in a Tristar 190.
I believe that engine is LH and the starter should be a CW (which is what the Arco 70200 is listed as). Can anyone confirm?

I put that same starter in my 89 Tristar. Nice product, it seems like the starter spins the motor over faster and the new one was alot lighter than the original.

New Arco starter.
Thanks for the quick response J. Thought I had it right.
Oddly, starter has always worked with no problems, although lately has developed the slow crank when hot issue. I removed it while I had the manifolds, risers, and mufflers out to get to and fix a leak at the transom exhaust flange. Cleaned the starter up and just for kicks took it to Autozone for a bench check. It didn't fire the bendix out, just spun it at full speed. I then jumped it with 12v at the house, it was only turning over very slowly. It's 25 years old so I guess it was time. In case anyone else reads the thread, Arco starter was purchased from Marine Parts Source for $121.46. New wiring was included to the starter relay. Straight forward rewiring requried (diagram included).
Thanks again.
