Thank you Marc for responding. I put some photos of my boats in my profile, including the serial number on engine block freeze plug, and no zero, just starts with a C, as pictured. It is a 3 cylinder as you said. As for the load, I guess I'd have to call it light, as it was just me and the wife, and my normal gear, life jackets - anchor - tool kit - and fuel. Being that I don't have passengers aboard, would that be considered a light load?
I would imagine if I had a few passengers on board, it possibly I guess could drop it down to the 5250 range. Only one way to see, and that's load it down and see. For now, I'm just not pushing it past the 5250 mark to save the old motor. It's a noisy thing to me. I've never had a pontoon that didn't have a seat over the top of the engine, blocking some of the engine noise, and as the pictures will show, its just wide open for noise to spread. I bought it last year at end of summer from the original owner. I had to replace coils and ignition wires, cleaned the carb system just by de-carb method, but it now runs like a champ. My prop has a few minor chips and dings, so I plan on replacing it next year, that's when I will make the move probably up a pitch or so if needed. If as you said me and the wife and gear is considered a normal load in your opinion, I think I need to move up a pitch, don't you? Thanks.
