  1. Allison Trans M20 pump leaking

    Seeing if anyone has any feedback or experience with these pumps. I have a slow leak coming from the transmission pump on our STBD 6V92. I am having trouble finding info on these pumps. The little info I have located has mentioned there’s rebuild kits for them. The gaskets and O-rings dry up and...

  2. 2nd generator on a SF

    Not thinking about it, going to add one. Ran the boat inland to get away from the storm to a spot that has no dock power. Something is going on with the pickup on my existing generator where it’s getting air in the Racor and seemingly starving for fuel. Running only one AC was going well until it...

  4. Sanitation hose for a 40' DC

    Started changing all the sanitation hoses on my boat today. I couldn't remove the hose from my guest head to the ER vacuum tank. Spent about 3 hours trying to pull the old hose out. There must be a clamp somewhere that I can't get access to. I removed the one under the guest sink and can't see any...

    I'm getting ready to change out the coolant in my 8v92TA's.

  7. Diesel Leak Found! Best way to repair?

    Hope everyone is doing well. We caught a whif of diesel in the aft cabin this season and last. I found the leak is on port side, just forward and under the aft shower. Original lines are mounted along the stringer. A couple drips per minute. Diapers for now. What route would you all go? I can...

  9. Finally getting close to the right prop size

    After running last year with the wrong ratio transmissions and this year with the wrong props, I finally got pulled and tried on another set. All year I've been running 30 x 28 4-blades and I knew I was underpropped as I was hitting 2400 rpms and showing 87% load. Cat rates the C8.7 as a 2300 rpm...

  10. Slimy stuff clogging my fuel filter

    Ever since I purchased my 1980 Hattaeras 37 with twin Detroit Diesels in 2014 I had a little hazy fuel in the bottom of my Racor filter bowl and my fuel filter on Port engine would clog up sooner than the Starboard one. I replaced the rubber "O" ring on the deck filling plug and in 2019 I got the...

  12. Can anyone tell me what the material is on the bathroom walls?

  13. 12V71 32V Alternator Question

    I'm pretty certain my port engine alternator is not working. I'd like to verify it's the alternator by testing output directly at the alternator. Can anyone tell me which leads I should be checking to get the 35 ish volts? I'm guessing the leads marked 1 and 2, then move to 1 and 4. Also not...

  15. Repower Questions

    Hope everyone had a great season! A local shop brought up the repower conversation. While we are quite a ways out from anything like that, it had me thinking a bit. These may be simple questions to some, so apologies in advance. With a new engine being smaller and lighter, what are the weight...

    Took the boat out fishing this weekend. On the way back in the starboard tach started jumping all over the place but the engine was not. It finally started pegging out then wound up back to zero with no movement and digital hour meter in tach not working. I was able to deduce the issue was on the...
