Maybe your mic is sensitive to valvetrain noise but from here it's sounds horrible.....way too much clacking. And yeh, that is a bunch of smoke coming from the valve cover. Can't tell you if real bad or not, unfortunately, from my computer screen.
Do the valves clacking sound bad to you in person ? |

Do the valves clacking sound bad to you in person ? do they sound good?? No. Do they sound as bad as that video?? Also no. Honestly it sounds about like most old carbed motors I have been around. Far from perfect but definitely not as bad as that video sounds. I could definitely believe there is a piston problem though... I've ran the boat pretty damn hard honestly. Hard enough to know it'll see a true 68 and that above 55 in 3 footers the throttle work is almost too much to handle. |
Will it still make the same power as it did when you bought it?

It was down on power a bit last time I had it out, which was Saturday, didnt want to plane off and wouldnt go over 4k. Yesterday during my trial run around the harbor, it took forever to plane off with just me in the boat, could only see 2k on the hole shot and 3k once I was finally planed off. |
Also, are you in the water or have a water hose hooked up just now? If not, you most likely smoked an impeller.

its stuck around 3,000 rpm in gear but at idle seems it will go higher... havent tried to rev it up too much at the dock because this thing is straight piped and excessively loud... don't really want to make the neighbors mad.

You've burned a hole in a piston or pistons.

Would it be safe to idle a mile to the boat ramp or am I going to need to tow this thing?

Tried to PM SB but his box is full. He'll be back though.............

Can't answer that as it may or may not makes things worse. Your call.
When you get into the diagnostics and repair, keep us informed and ask as many questions as you fell like. In the mean time, did the previous owner leave you with a detailed list of the engine build ? |
