Hello,

First post here, and let me say that I have thoroughly enjoyed and appreciated the expertise here about the volvo engines/outdrives. I have used the resource several times.

Ok so basically here is the problem.

I recently purchased an older 250 sportsman circa 1990 with a penta 570 and 290A outdrive. Overall the boat is in excellent shape for its age and the previous owner had spent more than the price I paid in upgrading it over the last 2 years. New wiring, and rebuilding most everything on the boat. The boat looks great, and is mechanically sound for the most part.

Now the outdrive had been totally redone, new bellows, new u joints, etc. The motor started up first time for 6 months and ran beautifully. I will say up front that while I am mechanically inclined, I did not really have a lot of experience with I/O and outdrives or boat engines for that matter. I would like to think that since I have changed a head gasket on a land rover and fabricated my own parts due to necessity that I can follow instruction pretty well and understand the workings of whatever I am working on.

Ok so here is the recent problem. I started to notice water in the bilge, and I began to suspect a faulty drain plug o ring and sure enough, there it was. The threads were also worn badly (plastic) so I decided to replace the entire plug & housing.

So I went to raise up the engine (as I always store it in the down position on the trailer) to make some room to work and SWOOSH..... there goes one of my hydraulic trim hoses, big hole, fluid all over the bilge.

Glad this happened on land.

So I removed the old hose and fittings which were VERY corroded.... I had to cut it because the ends would not spin.

I have the new hose (actually I bought two since I found used ones in excellent condition from freshwater with no corrosion and no cracks or fray in the hose). I have decided to replace only the one hose that burst, and keep the 2nd as a spare for now...in case this happens with the other hose since the other hose is VERY hard to reach.

Now the question is this:

After I put the new hose on..... is there any procedure I need to take before operating the trim?

I assume I need to top off the fluid reservoir, but is there anything else? bleeding? or will it self bleed? (im thinking brake lines here :)

its self bleeding all you have to do is fill it up and cycle the trim up and down a few times and top it up again (with the drive up)

ATF is the fluid you use. The reason it's pink is because of water in the oil.

wait,

help me understand.....

water is purposely in the ATF? or it got in there?

either way i feel like I am just going to top off with ATF right?

or should I bleed it out....and replace?


any special brand of ATF?

No water should be present in the system. Is the fluid really pink or red? Regardless I'd purge the system and refill. The older drive like yours can use either motor oil (10W30) or ATF Dextron.

Re: Greetings and a 290A question :)

well,

looking thru the tank its pink....

but i suppose i will do a more thorough investigation.....

whats the procedure to remove all fluid?

and further....how do I not get water in there again? :)

for the record, I do think the tank is kinda "loose" where it attaches to the housing, but I will check tomorrow....

If it is a "clear" pink it is probably ok. If it is a "milky" pink that indicates water contamination.

Take the cap off the reservoir and look inside instead of looking through the reservoir, is it still milky.

If the housing is loose, and rain water gets on top of the reservoir, it would get into the oil. Or, the trim cylinders themselves could be leaking and allowing water in the system.

No, don't mix types of oil. Get some ATF, even 7 11 carries ATF

Don't mix the oils!

The ATF fluid I use comes out of the bottle a clear pink. System should be self-priming so as per above, refill and run the cycle a number of times.

You suck it out of the reservoir with something like a turkey baster or suck it out with a pump of some type. Fill with fresh fluid and run the drive up and down a few times. This will mix with the old fluid. If the fluid still looks milky do it again until the fluid looks relatively clear. Then put the drive all the way up and top it off. Lower the drive as it should always be stored in the down position. Done.
