Hello everyone!!
New here and need help!!! Got the boat out this year and there is a crazy loud knock in the engine compartment. The boat starts great, idles great and revs great. Put it in forward, only while in the water and around 2500 rpm theres a crazy loud knocking noise. It wont do it with the muffs. At first I really thought major mechanical, but it makes no sense on how good it runs. Has plenty of power. I found a video of the same engine on YouTube and its the identical noise. If i can figure out how to put the link i'll put it on here. The comments on that video stated it ended up being a head gasket. I just cant believe it though, runs too good. I've changed Spark plugs, Distributor cap, Rotor, plug wires, Fuel/ water separator, oil and filter, and even dumped 30 gallons of gas.
Boat is a 2000 Hurricane 2100 Sundeck
My understanding is that model did not come with a 5.7 and that this one was special order
Engine= 0L657312
Transom=0L853506
Drive=0L752803
