hi guys, I have a 84 johnson 90 v-4 that is not peeing and no top end at wot. the boat has sat up for 3 years. before I tried to start it, I dissasembled both carbs and cleaned them. not alot of crud in them but the jets on the left side of both carbs were stopped up. I cleaned and reassembled them and the engine started almost immediately under the muff. there was no water coming out the pee hole but thought maybe it had not come up to temp. I put the boat in at my launch and ran it out maybe 100 yards but would not rev up and plane. still no water coming out the tell tale so I brought it back instantly. I removed the engine cover and touched the heads but they weren't so hot you couldn't touch them. I ran a small piece of wire in the water outlet but didn't feel any obstruction. I was told by the best boat mechanic on the lake that this engine had a nearly indestructable impeller and it should be fine. So, for the questions, what should I be looking for as to (1) no top end, (2) no water at the tell tale? could the thermostat be frozen shut and if so, how hard is it to replace? I will pull a compresion check and report back. Thanks for everyone who has input to this forum as I have used it before and I know a lot of you offer your time and wisdom without much reward. I'm here to say a big THANK YOU!
