Hey All-
First, let me thank everyone on this list for all the knowledge I’ve gotten here. I’ve got my first boat last year, and the information I’ve gotten from this list has been incredible.
Ok, on to business. I just put on a new (fresh from generator) GPU to replace a worn out one. I installed a CHT gage while I was at it with the thermocouple installed on the left middle cylinder. I took it out for its first shakedown run this morning. Calm day, temperature in the low 60s. Great morning for a ride. The new motor ran great! However, the CHT gage came up to almost 500 degrees with easy running, and hit 550 when pushing it fairly hard. Oil temperature barely registered on the gage. Seems way too hot, especially on a cool morning with just my skinny butt in the seat. What do the rest of the GPU folks do to keep cool? Does anyone make a good shroud for this engine, or anyone have tips for building one?
Thanks for the help.
