Re: Force water exit holes??
you should get a slight spray only at idle out of the 2 "idle relief" holes that aggitation is the exhaust coming out of the snout above the prop. if you see no water coming out of the holes at all, I would check the impeller just to be safe. Do you have a "plug" threaded into your t stat housing? if so you can put a nipple on it with a tube to make a tell tale
