Thanks potbelly and Craig for your replys!
I came across a pdf file manual for the md6a and md7a online and printed it off. Will be super helpful.
potbelly about the hull speed
and prop size didn't think of that. Was thinking that (bigger more HP) would be nice to fight the currents.
The reason I was thinking md17 instantly because it was for sale
for 750 running and was thinking it was going to cost me more for gasket
kit and possibly new head, machining etc.
Found some measurements on beta marine
for the md17 and md7a and the engine will be to long for my engine bay.
I went to the boat this morning and took the motor
apart to investigate further. Luckily it looks to be just a head gasket. The gasket broke apart right beside the aft cylinder and cooling
port hence the water into that cylinder.
Now that it's all apart i'm going to clean up head and manifold. I will source new gasket kit and thermostat kit clean and put all back together.
My concern is why the gasket broke at the port in the first place. The hole is a little elongated I guess from years of wear and tear. Should i put some gasket glue around the water ports
when I reinstall the head gasket??
Besides that everything looks to be in Great shape. Cooling
manifold isn't clogged seems to be clear but will clean anyway. Going to give block and head a light sand and clean up. Reset the valves, check the thermostat and change most likely anyway as a precaution and cross my fingers.
Dodged a bullet...maybe!
I did find a crack in my exhaust elbow
which would explain some water leaking into bilge
when running. I will maybe get it braised or welded.
Took a couple pics and will post more as I go.
You guys know of any good sources for head gasket kit etc?
Called local marine
store today and they are going to get back to me.
Good to hear you got some parts Craig, I will keep that in mind moving forward. I'm sure I will come across things I will eventually need along the way. Possibly a exhaust elbow
if it can't be fixed. Also reassuring that the other engines will bolt up to the 110s just incase.
