After further investigation I discovered that the tube running through the exhaust manifold that heats the choke was not fully seated so the exhaust was blowing out the bottom hole. I pushed the tube down to cover that hole and all is well. What a relief.
I'm bummed I just reinstalled my 165hp L6 engine in the boat. No oil leaks, no water leaks, starts right up and idles smooth. All good except for an exhaust leak I can hear. I put my hand up under the exhaust manifold next to the block and can definitely feel air blowing down from between the...
I might try to tackle removing my engine to fix some suspected leaks at a rear core plug. I've pulled and replaced small block engines from classic Ford cars and trucks so I'm sure I have all the tools to pull the engine from a boat. I know I have to pull the outdrive first, but is there...
I've owned the boat since 1993. I live in an area that hardly ever freezes. The few times the temps have dropped to 32 degrees I've always opened the pet **** and drained the block just in case. I'm keeping fingers crossed its just a leaky core plug and not the head gasket or cracked block...
What could have damaged the core plug? I'm thinking simply the age of the engine and normal deterioration. The engine has always run fine, never overheated.
Bondo, now I'm really concerned when you say "fatal with no possible repair". Do you mean if it is indeed a leaky core plug and I don't fix it now, the engine will be damaged beyond repair?
Thanks all for the advice. Is that an expensive job to have a shop perform? If I go ahead and have the work done, should I have them change anything else while the engine is out?
1978 165hp inline 6 Mercruiser. I noticed water dripping below the engine only when the engine is running, either in the water or on the ear muffs. Was dripping right down the face of the flywheel cover plate so I dropped the plate down and videoed the drip. I don't see any leaks up the...
I also thought they are trailer guides but the vertical arms are so short and without the foam pad on that arm, it looks like could cause damage to the hull if the boat doesn't approach just right.
I inherited a box full what looks to me like rollers or guides for a boat. Maybe they are meant to be mounted on a boat dock somehow? Or maybe they're for a boat trailer? Can someone tell me what these are? Each one has u-bolts that appear to be for attaching to "something".
Well, got her started and running fine again. I usually don't like to just throw parts at a problem but for the price of a new condenser, I thought what the heck, it's been about 5 years anyway. Fired up and idles fine again. Thanks for all your input.
