Re: "Newer" 25/35hp OMC compatibilities

I’m getting ready to run it with no thermostat to see if it was a faulty thermostat. What has me itching my head is that it was running at WOT continuously for 2-3 mins and had no overheat issues (Ran fine at 143-158, temperature dropped quickly upon throttling back), yet I’ve seen it get hot, as if there is no water circulating around the cylinders, a handful of times.

The water from the telltale gets real hot during this situation, and from experience that tells me water isnt circulating, yet it’s pumping tons from the telltale.

Borrowing a page from my learning curve with the 9.9/15’s. Oh joy, good to know these bigger 25/35 motors act the same way with their water tube grommets.

Thanks for the reminder, and head’s up Danny, I remember you mentioning this to me several months ago, but had forgotten until now.

Will report back shortly.
