So I have question. I have a 2006 Volvo Penta 3.0. Why is when I crack the throttle and return to idle quickly the 4th cylinder pulls water in. Just enough to make it miss. Then I bring the engine up to 2,000 rpms and it comes out of the miss. If I slowly bring the throttle do I have no miss. Any help is much appreciated. Thank you
That could be a crack in the cylinder head, or bad head gasket. I’d lean more on the head gasket as there is more water pressure under load. Hope this helps.
I just bought boat with this engine but I have few issues... Acceleration lag, engine stalls at gear quite often - can be solved but adjusting idle speed to 1200 which had previous owner and thats crazy high imo.. whats normal idle speed for this engine? and last but not least i get only like 4 - 4,2k wot rpm.. Any thoughts ? :)
Carb rebuild is a def start. Idle should be around 650-750 idle under load. As far as the wot issue, I’d check for proper adjustment on valves or possibly a worn camshaft.
Thanks for all your help dude. You saved me a bunch of money.
Glad I could help
