    Cracked MS3 transmission heat exchanger

    A Volvo Penta mechanic said that I can just bypass the transmission heat exchanger as long as the transmission isn't cracked from the deep freeze. He said that those heat exchangers for my application don't really do anything important since the transmissions never get that hot enough during...

    Cracked MS3 transmission heat exchanger

    I thought I had prepared enough winterizing for the upcoming winter storm last month, but it wasn't enough since temperatures went way down to single digits! I found out that my heat exchanger on the starboard engine MS3 transmission is cracked! The motors are 1981 Volvo Penta BB140A's. Port...

    Outdrive will not raise up!

    1996 Volvo Cobra SX sterndrive trim button on the shifter handle (Morse) works on the lowering function, but now you flick the button up on the shifter and nothing! No sound, nothing. I tested rocker switch button inside of shifter and got 12.75 volts on both up and down wires, I also pushed red...

    Stray sparking from coil to distributor

    During warm up I noticed the tachometer needle was bouncing around and the starboard engine was starting to idle rough. I noticed there was arcing between the positive Pertronix wire from coil to side of the cast iron engine block half way to the Pertronix in the distributor. There wasn't any...

    Links to instructional Videos or PDF on timing belt replacement

    I am in the process of changing out the timing belt in a 1981 Volvo Penta BB140a (B21). Can anyone share some links on how to instruction videos or PDFs?

    Weber/Redline conversion kit

    I've read older archived posts on dumping Solex sidedraft carbs and the successes converting over to the Weber/Redline kit. Where is the best place and prices to order a conversion kit (K861) for my 1981 Volvo Penta BB140 4cyl engine? I'm done with Solex!!

    Engine dies after warming up

    My 1981 Bayliner 3270 has twin engine BB140A's with each motor sporting I believe are twin Solex P44PHN3's. The starboard engine starts up great and I run it at 2000 rpm during warm up, but after initially warming up to 170 degrees, I idle it down to the factory idle speed of 900 rpms. Then the...

    1981 Volvo Penta MS3 transmission

    Is there a place locally I can box and ship my MS3 transmission to get rebuilt? I live in SW Washington state (Washougal).

    V6 Ring gear replacement

    I need to replace the ring gear in my 1996 Volvo Penta SX cobra 4.3 V6. Question- is it easier to just replace the outside ring gear or just order a whole brand new flywheel for that application ($289 on Amazon)? 2nd question- Are all flywheels the same for a Chevy V6 (S10 and Volvo Penta)?

    Unsteady timing mark

    I own a 1981 Bayliner 3270 powered with twin Volvo Penta BB140A's. Both motors have Pertronix that I installed over 12 years ago. Both run great with the Pertronix! Yesterday I was checking the timing on both engines starting with the starboard. Timing was around 11 BTDC which I lowered to 8BTDC...

    Ignition timing procedure for 1981 BB140A

    All I can find in my Sea-Loc manual are timing specs! I need to know if there is an advance canceling involved prior to timing adjustment? Also the batteries are too far away for my timing light to clamp on to. Can I use the + on the starter and block for a ground? The manual doesn't even give...

    Running two different motors off of one gas tank!

    I own a'96 Campion 622 Explorer sport fishing boat that I recently installed a brass 3-valve (Sierra Marine part #18-1656) to switch from main engine to trolling motor and vice/versa from main tank. It works fine, but I have to open up the motor cover every dang time to manually switch it over...

    1981 Volvo Penta transmission shift issue solved??

    My 1981 Bayliner 3220 runs twin Volvo Penta BB140A's with MS3 inboard transmissions. For years when you pushed the black shift lever forward on the port engine, it took about a minute to engage fully! Last summer I changed out the transmission oil in both. The oil was pretty old, dark and stinky...

    Distributor module 1996 4.3 GS

    Are all modules on the distributor the same for EST type of spark advance systems? Chevy S10, Volvo Penta? I'm thinking about replacing mine because as I wrote before- my rpm/timing doesn't change when I apply shunt cord to the back of the distributor when I'm adjusting the timing! It use to before!

    2005 Honda BF8 fuel line connector

    I just purchased another Honda tiller motor for my Campion 622. I thought that I could use the same portable tank and hose connections from my 2000 9.9 Honda. The 2000 hose connects to the 8 horse, but leaks badly, especially when pumping the fuel line ball! I thought they would be...
