Hello all,
Hoping to find some technical links from you guys who've been there done that on one of these.
My stbd engine took a dump before I even got on the water. Narrowed it down to the most fwd cylinder. Zero compression reading.
Pulled valve cover, timing chain appears intact and tight. I'm guessing one of the 6 valves or springs is bad. Kind of shocked they did 6 valves per cylinder.
Any leads is appreciated. Hesitant to tear into it with no manual.
