Had the boat out 3 days the last weekend and was running with some "extra" relatives on the boat playing around. The boat was getting pushed pretty hard on the 85HP Force in terms of weight in the boat and tube. Getting up to plane to pull a tube was slower then usual with less weight and that makes sense. It was going great until I started feeling an intermittent drop in the engine power. This happened sporadically but did not seem to really get bad or feel like the engine was going to die. Through the day I stopped and it started up no problems at all. The last drop was bigger than the few times before and I did not want to stop so headed back to the dock. It was dropping in power a little but ran all the way back... Let it sit for about 30 min. Decided I did not want to get stranded so I was going to pull it out. The engine started it up to go to the ramp, started like a champ, no issues. So I went out with a couple of kids and ran around no problems at all at close to WOT with "fun" turns and straight with no problems, through the power range of the throttle... Getting late so I still called it a day..
Question is what would cause the drop? Would working the engine pretty hard for an extended time cause this? Maybe it was getting hot and that created the loss of power? Completely Fresh tank of Gas at a 50:1 oil ratio and the primer bulb felt full... At home I pulled the Thermostat and it did not look great but when I tested it it in hot water opened. Figured I will get another one as it is only $30 or so to just know that is not it. I have a "Tell Tale" I put in and it was flowing. As the engine was used, hotter, I noted that the flow took longer to start and that maybe it was not as strong. I have an Impeller kit on the way and it should be here this week to replace the current one.... I had not changed it so it is time anyway..
Can the extra work load and being used hot and hard cause this drop? It did not skip and while running seemed to run smooth until the power drops. I hate to lose confidence but I have a little. Another time it dropped power then started and then died. that was because I foolishly believed that there was a 1/4 tank left based on the fuel gauge. Now I know it reads wrong :redface: which is not the case in this instance..
Any opinions on the power loss.. I think I gave about as much info as I know..
