    Main Crank Pulley bolt

    VP AQ120B OHC is the main crank pulley bolt standard thread or reverse? Any good suggestions on how to get this bolt out? Any tricks on holding/seizing the engine? Not sure I have enough room for an impact wrench. Thanks. It looks like I have bad oil seal, not leaking too bad but just started...

    Replaced head on VP AQ120

    New head gasket, do they still require re-torqing after a few cycles of warm up and cool down? If so, Do you experts just do it after a brief warm up? BTW the number 4 and 3 exhaust ports were corroded beyond repair. There was nothing left. I always flush with fresh water after a saltwater...

    Pinging Old school VP mechanics. Impeller kit for seawater pump

    I received an impeller replacement kit for my VP 270 / AQ120B seawater pump. It comes with a tiny vial of green looking stuff. What is it and what do I do with it?

    Condensation in fuel tank

    I recently posted about excess condensation in my engine causing the oil to turn to milk shake. I fixed that by a couple of oil changes but now I'm concerned about excess condensation in my fuel tank. Is there any way of getting rid of the water? I'm little concerned about the boat breaking down...

    Water in oil scare, not always the worst case.

    Just a headsup that sometimes water in oil isn't the end of the world. Or a cracked block. It seems a lot of guys find this out this time of year when coming out of winter. As I was de-winterizing the boat and getting it ready for summer, I noticed the dreaded milkshake on the oil dip stick...

    270 outdrive removal, I think I screwed up!

    I read the online manual instructions. It said to loosen the helmet nuts before punching out the swivel pins but it did not say to remove the them or the helmet. Well I turned the outdrive and punched out both swivel pins, one came out the other is pinned against the helmet and won't go any...

    Wandering Ignition Timing

    I've got a head scratcher. 1981 AQ120B with Hot-Spark Ignitor. I've noticed in the past year my ignition timing moves. Not all at once but from one or two trips out to the next. Once the timing is set, the boats starts easy, idles great, revs like it should. Get great gas mileage too. Then after...

    AQ125B head on a AQ120 block, any problem?

    As the subject says any problems putting a B230 head on a B21 block? Will it fit? Will there be any interference issues? Most parts seem to be the same.

    AQ120B B21 head replacement

    As some of you might remember I had the dreaded #4 exhaust port corrosion causing an exhaust leak. I had the idea of a quick fix by JB welding it but it only took about 5 hours of running time to fail. I'm sure there are other products out there that can stand the heat better than JB weld but at...

    Water spewing out of the seawater strainer cap.

    SO I finally took my new boat 1981 Bayliner Explorer 2270 out for a maiden voyage and shake down cruise on the lake last Sunday. I came back with a few issues but nothing really serious but I have some questions. The worst problem was having water spewing out of the cap on the seawater...

    270 drive reverse safety lock adjustment.

    How do you adjust the reverse safety lock mechanism? I replaced the original rod with a bolt of similar size and now it won't unlock with the trim button. I think the bolt i used is the cuplrit but it's impossible to find the original rod. I can unlock it manually to lift the drive. It looks...

    AQ OHC 4 cylinder water pumps, rebuildable?

    I am in the process of replacing my timing belt and tensioner and (if this were a car) I would change the circulating water pump out as well since they aren't expensive. In fact i bought an auto pump for cheap but come to find out, Volvo-Penta pumps are different. The outlet for the auto is for...

    Exhaust Manifold gaskets AQ120B

    Curious about different brands. The Beck/Arnley have a steel (stainless?) innner ring on their gaskets but the Volvo-Penta brand doesn't. They are about the same price. Would the Beck/Arnley last longer? Or will the steel rust and corrode faster hence the non steel ring on the VP? Curious before...

    AQ125 throttle linkage : can anybody snap me a quick pic?

    I'm trying to convert my AQ120B intake to a downdraft from a AQ125. I'm amazed how different everything is. I can't figure out the linkage to the carb. I'm sure the cables are the same but I would like to see how throttle casing attaches to the motor/intake. Thanks in advance.

    AQ120B Intake gaskets, can I use one for a 2.1L auto?

    I need just the intake gasket. All I can find is an entire head gasket kit for $160+. I can find a 2.1L volvo intake gasket for a car for about $6 is there any problem using one for a boat if I match it up?

    I'm Back!

    It's been 4 years since my last VP powered boat. Ah fond memories of an AQ140 and those side draft carbs. I just bought a 1981 Bayliner Explorer 2270 with an AQ120B and 270 drive. It seems to be in good condition. The previous owner had enough confidence in it to go over the Columbia River bar...

    Priming a fuel system w/ water fuel seperator.

    Anybody do this? I burnt my battery and heated a negative cable pretty bad by using the starter motor to get fuel to the carb. I figure there has to be a better way. Starters on my boat aren't cheap if you can even find one (MCM470). I don't want to burn it out. I put a new water/fuel filter on...

    470 owners, what prop size?

    Having problems with RPMs and prop size. What prop sizes are you running. What drive ratio do you have, RPM range are you cruising and what speeds are you getting. Also what size boat do you guys have. I have a 14" x 21P but my RPMs vs speed are way off. Anybody running a bigger prop? Thanks.

    RPM troubles, need some input. 1982 470

    1982 19' cuddy MCM 470 As some of you might remember I replaced my upper this past winter with a different one thinking that my current upper had the wrong gear ratio (1:1.98). The stock came with a 1:1.84. My rpm range is 3800 - 4200 but I can reach way higher rpm than that. And cruising in...
