Ok, now I do need help. The issue continues to be M/C 3.0/140. The initial problem noticed was oil blow-back through the dip stick. Further inspection found water in the oil AND visible water spraying out between the manifold and the head just aft of the #2 cylinder while the engine was at idle...
I?m sure this question has been answered somewhere, but I am in a pinch and need a quick answer. The kids want to ski!!!
My Mercruiser 140 has a crack in the head and needs replacement. I have located an OMC 140; however, the ports on the head are not the same. The intake ports are not divided...
We have an older M/C 140hp (mid ?70?s) that is now in a deck boat and has always run just fine; even to the point of being able to jerk our 19 yr/old our of the water on skis. Then this past week it developed some rather odd problems that have us a bit stumped on how to best approach a solution...
Give me a MerCruiser and I am a happy puppy. :D
Unfortunately, our teenage son found a Yamaha jetski and it followed him home!! :eek:
So here is my question ? This jetski is a ?94, model: WRA700 S. The engine is in need of a rebuild and we want to replace it. The current engine data plate...
I need to get this boat finished and then ready for winter, so before I start tearing things apart (or pulling what is left of my hair out!) I would appreciate a bit of wisdom from anyone who might care to comment. I am confident that the answer is something we are overlooking:
The original...

Not being a mechanical engineer, I need to seek additional wisdom. What effect on WOT and prop pitch should be expected if you marry a late ?60?s (1968) 120 Mercruiser power plant with a mid ?70?s 140 outdrive? I know that the original 120 stern drive (sr#2366557) had a ratio of 2.01:1, and the...
Currently working on a restoration of a 1968 20ft deck boat manufactured by Golden Triangle Manufacturing Corp in Euless, TX ? SR# 20D8007. Powered by a 120 Mercruiser. An internet search has not provided any information. I would appreciate any information anyone might have concerning the Golden...
Doing some restoration on older Mercruiser units. I know that most of the Mercruiser Service Manuals from #6 on are available on line; however, does anyone know if service manuals #1, #2, #3, #4 or #5 are available anyway online? Many thanks -
