I just recently changed my trim pump on my AQ290 outdrive and feel I might have mixed up the pump hoses. The pump is slow as molasses lifting and really fast lowering. In the AQ290 service manual the diagram I saw on the old style pump 852928 does not show the transom shield diagram well...
I have an AQ290 drive with the old style pump. If I trim it up it slowly drops down to negative trim over several hours, or faster when under power. I read a thread about some of the AQ290s have the new style pump. The electrical diagram is different for old to new pumps. Do I have to replace...
I have a 26 foot Cruisers, Inc. with an AQ290 DP outdrive. I put in a rebuilt engine this Summer and ever since I have had dead or low batteries (dual). I have had to keep it on a charger all summer. When I put the voltage meter on the hot alternator lead I get 13.7 volts. The indicator on...
I recently rebuilt my intermediate housing or Bell housing on my AQ290 drive. I removed the clips and used a brass drift to drive out the shaft. It all went back together fine. Today I tried for over two hours to put the gearbox/ujoints onto the shaft and never did get it to happen. Would the...
I am almost ready to put my rebuilt 350 Chevy back into my boat with an AQ290 with DP. My question is I can see one oring since it was on the back of the intermediate housing when I pulled the engine. I can't see the second one. I did not pull the outdrive, I only pulled the gearbox. The plate...
I was looking for a new timing chain cover for my rebuilt 350 Chevy motor and thought I found what I was looking for on eBay. Ad said "Brand new, unpainted with a weld on tab with marks on it". When I received it the tab was welded on - and in the wrong position. :eek: The marks are in the...
I have an AQ290 with a 350 Chevy engine. The engine is junk so I am repowering. Since I also had water in the ujoint bellows I read that I should change the bearings. I apparently tightened the clamps too tight and the clamp let go. Both the ujoints and the bearings seem fine. No end play...
I just looked at a 22 foot pontoon boat with a 60 HP Merc 4 stroke engine with power trim /tilt. I was wondering if these motors are reliable compare to 2 stroke models or other comparable 4 strokers? Also, how does the 4 stroke compare to the 2 stroke in terms of power and torque, since this...
Hi, My 1986 350 chevy, 260 HP motor needs replacement. It's part of the Volvo Penta AQ290 setup I have in the boat with duoprop. I want to explore what is the right option for the boat (26 ft Cruisers,INC. 6,500 lbs). Can I put a vortec engine in this boat or what other options might I have...
I have an AQ290 with a 350 chevy engine. I am trying to find the right motor flusher for that motor since the one I have doesn't seem to seal off the lower end well. The volvo lower end is a much sharper angle than what I am used to. Is there a special one for the AQ290?
My 60hp Johnson has a brand new water pump and vernatherm but the overheat alarm goes off at WOT and when I put my hand on the top of the motor it's not hot. Some one suggested I clean out the passages between the cylinders as bubbles can occur and cause this problem. What new parts,(i.e gaskets...
My motor would not shift and I only had reverse. After figuring out that the problem was in the lower end I removed it and found the shift rod loose from the lower end. I screwed it back in all the way but now the linkage will not connect. I noticed that some if the Johnnyrudes have a...
My starter was bad on my 5.7 liter AQ290 Volvo Penta. I mistakenly took the old one out before I got the new one, which by the way is much smaller than the old one. Since some of the connectors were corroded I cut them off and put new connectors on. Now I'm not sure how to wire the new one...
