So aside from the lower unit seals leaking, I would like to pop up my 18 horse a bit. Its on a 14 foot fiberglass so its no rocket. It just barely goes fast enough for the bow to start coming down to a plane. I noticed that the 20hp of the same vintage uses the same bore and stroke. Can anybody tell me the differences between them? maybe a carb or intake change from the 20 would help. I thought another couple ponies and maybe on of those wing looking things that bolts to the lower unit the boat may plane better.
