I'm fairly new to boating but I've posted a couple question in the past and you all have been very helpful. I'm not sure if this is the right forum to ask this question and I'll move it if I should. I live near a lake that has a 9.9 hp limit on the lake. It's a 3,000 acre reservoir but near a large city so they limit the hp. I recently bought a Lund 1700 which is pretty heavy for a 9.9 but since that's the max i bought a used 9.9 Yamaha four stroke. I had a little problem with getting it to idle so i rebuilt the carb and it runs well now. I took it out the other day and took it for a spin. When I was tuning up the motor it will run about 5500 rpm which it should. When i got it out on the lake and ran it WOT I could get it up to just a little over 4000 rpm under load. My question is, is this pretty normal and because I'm trying to push such a heavy boat with a small motor? Sorry if I sound so ignorant but I'm learning, with your help.
