    Volvo 3.0 GSP-A high idle

    I am getting the boat ready for the next season, and I still have a nagging issue left over from last year. The boat is a 2001 Larson with a Volvo 3.0 GSP-A and SX drive. Last year was my first season with it. It has been hard to get the thing to idle at low RPMs, and I have to have the...

    Manifold removal - Volvo 3.0 GSP-A

    I was going to pull my manifold to replace the manifold gasket and check it out, but it looks like the exhaust pipe that goes down to the transom blocks you from taking off the manifold. On mine there is a stud with a nut on it that is about 1/2 inch away from (and behind) the rubber exhaust...

    Holley carb throttle plate holes? (3.0L Volvo GSP-A)

    My quest for a low idle continues... Can someone tell me if the throttle plates should have small holes in them on a Holley-carbed later-model (2000+) Volvo Penta 3.0L with a PCV valve? (you can see if you look down past the choke) I'm trying to figure out why I can't get mine to idle at a...

    Help - can't get low idle on Volvo 3.0 GSP-A

    I have been getting this "new to me" boat ready for the last few weeks thanks to everyone here. I couldn't get it to idle below 1000 rpm even with the throttle plates fully closed, and I noticed some fuel leaking from the throttle shaft, so I bought a rebuilt carb from "Flying Fish". Now with...

    Gasket sealer on carb gasket?

    I am about to install a rebuilt carb on a 3.0L Volto Penta GSP-A engine. Should I use permatex or something on the gaskets? Also the spacer block that goes under the carb looks like there is not alot of surface area to seal to the gasket (and there are cavities that can accumulate fuel). Are...

    Volvo Penta 3.0L Carb throttle shaft leaking

    I ran my 3.0 GSP-A volvo engine today (on muffs). I cranked it for a short time and it didn't start at first, so I went back and looked things over. I noticed a drop of fuel coming out at the throttle shaft. I disconnected the throttle cable, and the shaft moves around quite a bit in the hole...

    Volvo SX drive - metal particles on magnet

    I am working on a boat I bought a few weeks ago. It is a 2001 Larson with a 3.0 Volvo and SX-M drive. I just spent quite a bit of time aligning the engine and replacing the ring gear on the flywheel, impeller, plugs, etc.. Now I turned to the drive to drain the oil and check it out, and I...

    Volvo gasket compound, grease, etc

    I am about to pull the Volvo SX drive from my boat and replace the bellows, and inspect the gimbal bearing and u-joint (I just got the boat a few weeks ago). In my Volvo manuals, it says to use 1161099 gasket sealing compound in a couple of places (like in the groove where the bellows goes)...

    Should I replace ring gear?

    I just got a boat (2001 Larson) with a 3.0 Volvo GSP-A engine. They had an alco aftermarket starter on the thing. The starter wasn't engaging all the way onto the flywheel ring gear (i.e. the gears overlapped only half way), and the starter gear was trashed. As far as I can tell so far, part...

    Non volvo oil in Volvo SX-M drive - OK to use volvo?

    I just got a used boat with a volvo 3.0 engine and an SX-M outdrive. The boat is a 2001 model. I test ran it on a lake before I bought it and everything seemed nice and quiet. It was always run in fresh water (according to the seller). The drive has non-volvo gear oil in it (it is kind of...
