Looks like it's time to replace the thermostats and blow off valve. The engine is idling below 140 degrees, and as soon as I throttle up, it drops way below 120 degrees instantainiously. Actually looks like the gauge is pegged cold.<br />Won't idle, fouled plugs, excessive fuel consumption, reduced WFO performance. (just like the Clymer maunal says for a stuck thermostat)<br /><br />Question: I've been told I should replace the blow off valve with a 1997 valve with the slots in it to avoid the "air bubble" syndrome. Should I also get the 1997 thermostats? Is there a "kit" for this assembly? Do they come in different temperatures? If so, which would you recommend for ocean trolling?<br /><br />thanks

I don't have my manual in front of me so can't be much help there. <br /><br />Why don't you just replace the old parts with the original OEM parts that came with the motor? They seem to have worked well up until this point.

I received the OEM parts yesterday. About $52 for the stainless thermostats, gaskets, seals, and the 1997 blow off valve.<br /><br />Question:<br />The 3 grooves in the blow off valve are pretty small, and the cross sectional area doesn't seem to add up to that of a 1/8" hole.<br />Is this enough area, or do you recommend drilling a small hole also, like a 1/16" in the center of the valve?
