manifold temp

No, I use the green stuff. I always crank it with the fake-a-lake in the driveway before I take it to the lake. While you're checking the hoses, take the thermostat out and look at the end of the bypass fitting that's to the left behind the thermostat housing. It has a 90 degree in it and I've found impellor pieces stuck in that thing twice.

It depends on the plumbing setup. When my thermostat opens, most of the water exiting the manifold will go out the driver side exhaust. The raw pump is on the passenger side and the T is close to the exhaust manifold on that side (for water cooling exhaust on both sides) and the water flow is crossing the thermo housing toward the driver side. I noticed this several years ago when winterizing my boat on a cool day. I noticed alot more steam on the driver side when the thermostat opened. And like he said, you could have some impellor parts stuck in the manifold, you should notice less water coming out.

after 40 min ride last night seemed to be running little warm, port side exhast manifold almost 50 degrees hotter. what?
