My boat has been docked since July 4th waiting for some repairs. I took it out for the first time last weekend and the max rpm I was getting was 4000 to 4100 rpm. Previously I was getting 4400 to 4500. Not sure if this reduced performance is because of the work I had done ( new computer) or the bottom growth causing more drag? I have been told that bottom growth would cause reduced top speed but should not effect top rpm. My mechanic says otherwise. Looking for some input on this as I just spent some serious $$$ on repairs. Thanks in advance

Thanks. 300 or 400 seem about right for a boat that has been sitting for a month over the summer?


Depends on type of water it was sitting in and how fast the growth is. It does effect it. I couldn't get over 3400 rpm and 17 mph. Took boat out sprayed and cleaned bottom and I gained 300 rpm and almost 4 mph.

It could also be distributor cap and rotor.

Wouldn't hurt to clean the bottom first and see what happens.
