    Can I leave my outdrive up?

    I've got a Volvo Penta AQAD41A diesel running a Duoprop 290 outdrive (1987 vintage). In order to combat very serious galvanic corrosion problems on the props, I've been advised by an expert to hang a zinc "fish" from the props. In order to easily attach and detach the fish, though, it is...

    Is your Volvo duoprop dissolving as you watch?

    My Volvo Duoprop 290 (1987 vintage) appeared to be dissolving away over a period of months. When great chunks finally started to fall off the blades, I called in an electrolysis expert. His measurements of the voltage in the water next to the props showed perfectly normal results, and he was...

    "Sterndrives are tablets that dissolve in salt water"

    A local expert in marine corrosion made this remark to me (except that he used the term "Disprin", rather than "tablet", because in Australia Disprin are what we toss in a glass of water and gulp down to get rid of that hangover headache.) Expensive tablet, though: my Volvo Penta Duoprop...

    Duoprop 290 anodes - is this insane, or what?

    Am I insane (quite possibly), or do Volvo Penta make life difficult just for the hell of it (also quite possible, I suspect)? See the picture: the prop shaft anode (upper anode) is a continuous circular structure. This means that in order to replace it (which needs to be done often in my...

    How to restart a diesel that ran out of fuel?

    In another thread, I recounted an episode in which my 1987 Volvo Penta AQADP41A died very suddenly in a sharp turn to port at speed. We believe that the quarter-full tank sloshed over to port and exposed the fuel intake (on the starboard side of the tank) to air. After a lot of cranking over...

    Morse gear shift is sticky in dual station

    I've got a 27' cabin cruiser powered by a single 200hp Volvo Penta and Duoprop sterndrive. I've recently replaced both upper (flying bridge) and lower (saloon) controls with Morse Controls. The controls on the upper station connect to, and move, the controls on the lower station - which in...

    Volvo Penta diesel overheating problem

    I've got a 27' cabin cruiser with an inboard Volvo Penta diesel AQAD41A (1987 model) connected to a Volvo duoprop sterndrive. Ever since I bought it several months ago, there has been a serious and unresolved overheating problem. Max revs are supposed to be around 3800 revs, taking her to a...

    Sticky gear shift

    I have a 1987 model 27 ft fibreglass launch powered by a 200hp Volvo Penta diesel and stern drive. I recently paid a good deal of money to replace the ageing throttle and gear shift controls and cables at both the lower (saloon) station and the upper (flying bridge) station. The mechanics...

    ORCA anchor windlass - HELP!

    Hi Guys Have never owned a boat with an anchor windlass until now, and am stumped as to how the darned thing works. See the attached pic. It has power for UP only, and the footswitch you can see in the pic activates the up-anchor bit. This works fine, as I found in my initial exploration...

    Hydraulic steering that just keeps turning...

    My recently purchased sterndrive 27' launch has hydraulic steering. The flybridge helm is fine, but the wheelhouse helm continues to easily turn after reaching either port or starboard extreme. i.e., unlike the upper helm, the lower helm can just be rotated endlessly after it should have come...
