    Self Centering Keel Roller

    Some years back I had a SR AJ that was a pain in the rear to center when retrievng boat. I installed Stoltz 12" delf centering keel roller and my headaches went away, at least ones associated with loading boat on trailer. Now, I am having similar problems with a 29' Proline V hull. I will be...

    Blowing Fuses?

    It has taken me almost a year and a half to get my Proline boat ship-shape. It has been an ongoing process of about 12 sea trials and I am still solving small problems. I have the std 7 lug trailer light hook up, but I keep blowing fuses when I launch boat into salt water bayou. The lights are...

    I have a 3/8 safety chain shackled to my bow eye and trailer wench area. My boat is 29' and 7500 lb dry. My trailer is triple axel 14,000 LB rating. I'd love to find something to strap down rear of boat, but I don't believe that there is anything practical.

    How do you know water seperators work?

    Back in the day before the E87 crap, water separators/fuel filters would do a great job of filtering crap that had accumulating in gas tanks due to condensation, breakdown and trash. I'd pour out contents every so often and see the water and crap that that the filter had collected and prohibited...

    transom plate won't come off

    Re: transom plate won't come off You will have to remove rotted wood (I assume your transom is wood) and replace with something, synthetic or marine ply. Go to lowes or Homeo depot and buy a wood speed bore tool. It just cuts circles in wood, but in this case you can get into difficult places...

    Trouble with Sierra 18-7331 Elecric Fuel Pumps

    I posted this elsewhere. I hope someone who has experienced my concerns can relate to me. I connected digital thermometer under band that fastens or holds Sierra 18-7331 pump to stringer. Band wraps around pump and looks something like a band or connector to attach coil to the block. The...

    Sierra Electric Fuel Pump Issues

    I just replaced automotive electric fuel pumps with Sierra 18-7331 marine that are connected to Sierra OP72533 low oil pressure switches. I have MC 350 Chevy blocks with 4 barrel Rochester carbs. They seem to pump fuel and motors run well, but they get HOT. They are not so hot that I cannot hold...

    Proper Oil Switch Location?

    As far as I know, there are two locations to install oil pressure or sending units on Chevy V8s. One is located near the distributor on the block and the second located near the oil filter, recessed to where it is almost impossible to examine for leakage or replacement on some boats (like...

    Best Size Trim Plane

    I posted this request under the Mercruiser I/O section, but some viewers in this forum may be able to provide a better response. I found out the other day that my trim system is woefully too small. I have hyd. 12x9 tabs on a 29 ft Proline. Bennett recommends 18x12 with down fins on the side due...

    Proper Trim Tab Size???????

    I found out the other day that my trim system is woefully too small. I have hyd. 12x9 tabs on a 29 ft Proline. Bennett recommends 18x12 with down fins on the side due to the limited stern area available to add larger tabs. Bennett doesn't make trim planes with larger than 12" chords. However...

    350 Chevy Compatibility

    I currently have two 350 Chevy v8s in my boat( Mercruiser Alpha 1 Gen 2) . Both motors have the complete rear main seal/crank (not two pieces), and the space where a manual fuel pump world be placed is cast over. The cam is a roller. I don't suspect that there is much HP gain due to the roller...

    Mercruiser coupler alignment

    I have aligned couplers too but now I am having problems that my friend and I cannot resolve. I recently replaced 1/2 rotted transom on 1994 pro line 2950 cuddy/v8 MC alps 1 Gen II. Outer skin (about 1/2" think) was OK. I epoxy 2 3/4" marine ply into spot that had been consumed with rot. It was...
