    1987 VP AQ-260 (GM 350ci) coupled to a AQ-275 VP outdrive. Installed a San Juan closed cooling system (half-system) on the replacement engine two years ago.<br /><br />I've read a couple of posts about low temperature thermostats leading to less than ideal engine performance and was wondering if...

    Hydro-locked engine

    First the particulars... 1987 GM Marine 350ci coupled to an AQ-275 Volvo outdrive. The original engine was replaced a couple of years ago with a new GM 350ci. At that time a closed cooling system was added to increase engine life. This was what was known as a "half-system" where the engine is...

    VP AQ-275 steering fork bushings

    I have a 1987 Volvo Penta AQ-275 outdrive on my boat. The bushings (upper and lower) in the steering fork are shot. Is it possible to remove the fork and replace the bushings without removing the entire outdrive? Neither my Clymers or Seloc manuals say much about the procedure.<br /><br />Thanks...

    Sloppy steering Volvo Penta AQ275

    Does anyone know how to tighten up the steering on a VP AQ275? When the boat was out of the water, I could move the outdrive quite a bit from side to side by hand without moving the steering wheel. I've seen some other posts regarding this issue with Mercruisers, and the answer has been to...

    Generic WAAS GPS antenna

    I recently purchased an older Furuno radar with a Si-Tex NavADD 9000 GPS unit. The Si-Tex unit is connected to the radar's CRT screen and acts as a chartplotter when you plug in the C-Map chart cartridges. The only thing I'm missing is the GPS antenna for this machine. I want to use this unit as...

    Adding extra fuel tanks

    I have 225hp Volvo Penta I/O on my 24' boat and I would like to add a couple of 20-25 gallon saddle tanks to increase my range. I only have a 57 gal belly tank now, and by burning 12-15 gallons per hour, I have a limited range if I go by the old addage, 1/3 out, 1/3 in, and 1/3 for safety.<br...

    Boat yaws at low speed -Help please!

    I have a 24' deep-vee hull with an I/O. I have Doel-fins attached to the lower unit for getting out of the hole and on plane quicker. I don't have trim tabs. My problem is at low speed (5 mph no wake). My boat yaws from side to side terribly. The bow will swing three to four feet in either...

    Gimbal Bearing replacement

    I have a 1987 Volvo AQ225 (GM 305 ci) mated to a AQ275 outdrive. I think the gimbal bearings in the upper drive unit need to be replaced (growling sound is noticable). Do I need to pull the engine to replace them or can I get to them by just removing the upper drive?
