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...
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...
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...
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...
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...
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)...
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...
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...
