    To Drain Or Not To Drain

    To drain or not to drain, that is the question. Wether it is better to drain you block after you flush, or leave the block full of water. I live in an area where I don't have to worry about freezing. I use the boat in salt water and flush with salt away after each use. I fish seasonally so it...

    Clamp Ring Seals

    The engine is a 1991 570A (4100116795), drive is a DP-A 290. I have it together and the clamp ring torque is supposed to be 20-25 ft. lbs. What I didn't know is the bolts actually keep tightening until they bottom out and the torque is just for the bolt. At least I am assuming they are supposed...

    Clamp Ring Seals

    Been looking on the net for days trying to find the procedure for installing a volvo penta 5.7 engine. I found posts about aligning the three tabs on the bell housing to center the large o-ring seal into the transom plate. I think I got that but can't find a damn thing about what to torque the...

    Primary Input Shaft

    Don't think I'm going to be putting a big block in soon, man that wrecked that shaft in the upper gearbox. Guess 3/4" engagement is enough !

    Primary Input Shaft

    I also need to find the torque spec for the clamp ring that seats the two-giant o-rings on the bell housing and transom plate

    Primary Input Shaft

    I'm installing a new motor into my boat. It's a 1991 Volvo Penta 570A with a DP-A 290 outdrive. I always overthink stuff, so while assembling the flywheel, flex plate and bell housing I decided to check to see how far the primary drive shaft (PDS) engaged the flex plate. It only in engauges is...

    Volvo Penta steering yoke shaft won't fit back into the tiller arm

    I got the job done. I got a chair, sat in the sun and filed every spline on the shaft and tiller arm multiple times with small knife and square files. I removed every micron of corrosion (and there wasn't anything significant that would make you think it was a problem). After about 2-3 hours of...

    Volvo Penta steering yoke shaft won't fit back into the tiller arm

    Thanks for giving some input. My manual mentions square splines but they are all the same on mine, no odd splines to match up. The tiller arm should be at 90 degrees to the yoke and the grease hole has to align with the zerk fitting (those are the only refferences I have for alignment)...

    Volvo Penta steering yoke shaft won't fit back into the tiller arm

    I have a Volvo Penta 290 DP and I needed to change the bushings on the steering yoke shaft. I was able to pry the yoke and shaft down with a couple of large pry bars to remove it from the splined tiller arm. Now when I try to reinstall the steering shaft into the tiller arm it won't fit all the...

    Water Intrusion Puzzle

    The number 4 cylinder was basically a water pump. Water was getting sucked right into the cylinder and out the exhaust. I got a set of remanufactured heads and almost got it back together, should run fine (if that one little shitty spot on the block deck doesn't cause an issue). There was no...

    Water Intrusion Puzzle

    I was mistaken, after a while some air was lost in the cooling system. I stuck my ear to the rusty exhaust port and I could hear air leaking into the cylinder. Looks like a head gasket. I'm pretty sure this engine is the original engine in this 1984 boat. Who knows what the water jackets are...

    Water Intrusion Puzzle

    Tried the water hose test, no water leaking into the ports. Nothing is ever strait forward :). Not sure what direction to go in now, guess the shotgun approach and do all the gaskets and replace that funky looking exhaust manifold.

    Water Intrusion Puzzle

    The cooling system held 15 lbs. Now I'm really stumped.

    Oh yeah, the boat doesn't have to be winterized where I live.
