Poppet Carrier fell in block

Re: Poppet Carrier fell in block

I think I have the 190 temp sensors, they look like the ones in the manual. Today I went out and did decarb, and a little fishing, boat runs real well and idles well in neutral, but almost stalls in FWD. I guess I need to adjust idle speed. I also think I have way too much prop. Everything seems to run well, but I can't get much above 5100 RPMs. Any suggestions?

The prop is a Quicksilver Stainless, and has a bunch of numbers then 25P stamped on it. Reckon this is too much? 18 Procraft Super180

Water temps vs Metal temps...<br /><br />You need to find out what the sensor is measuring!!<br /><br />And I would check spark on all the cylinders.... One cylinder not firing could cause a loss of 500+ rpms at WOT...

I do have spark on all cylinders, checked with timing light yesterday. however, I do have plugs on order and will see if that helps. Did decarb as iboats prescribes today. How would i determine which temps I am measuring, remove the sensor?

Is your temp sensor screwed into the block or held in place with Y shape keeper and one 1/2" head bolt? If it is screwed into the block/water jacket you are measuring water temperature, not metal. My sensor touches the head/metal. So it measures metal temp.<br />Thermostats should open at 143 degrees. Overheat sensor should go off at about 240 degrees.

I believe I have the water temperature sensors
