    Lug nuts losening?

    I have an aluminum 3 axle 13500 lb rated trailer with ss disk brakes. In the past, I had a master cylinder solenoid malfunction which appear to have caused premature brake failure. Although, it was supposed to have diverted brake fluid back to master cylinder's reservoir, it wouldn't. Thus, my...

    Installing new gas tanks on a Proline 2950 Cudy

    I have never been found of cuddy cabins on large boats. Small ones are ok. I have an older boat and have finally gotten her ship shape. It was hell. I installed larger tabs but they don't appear to be able to overcompensate for the rear end weight of two MC I/os and two 100 gal gas tanks in the...

    HELP!!!! How do I re-install cupped "o" ring

    Trying to eliminate any possible reasons why my disk brakes failed prematurely, I took a fellow forum member's advice and examined my master cylinder's insides for a valve required for drum brakes but not disk brakes. I was hoping that the manufacture had mislabeled the packaging. Yet, mine...

    MC Oil Pressure?

    I have 1994 MC v8 IO's oil pressure sending unit that I feared was providing incorrect reading after it warmed up. So, I connected a manual gauge/sending unit that uses true oil pressure. It has a translucent 1/8" tube that runs from 1/8 NPT connected at block, which connects to gauge. At...

    Sierra Thermostat Life?

    I replaced my thermostats last summer in both of my 1994 MC Alpha 1 Gen 2 350 V8s. They were Serra raw water stats and supposed to break at about 142. I got very little boating due to other problems. A month ago one motor's temperature alarm went off at about 220, and yesterday the second...

    Boat Curtains?

    This may be incorrect forum? I created my own external curtains on a 1986 SR AJ but don't remember what gauge of clear vinyl I used for them. I believe it was 20 gauge but it may have been heavier. I understand that there is 40 gauge now available, but I don't know if my old Singer or Kenmore...

    Disk Pads Failing??????

    Years ago I owned a SR AJ and hauled it with a triple axel trailer with one axle having galvanized drum brakes initiated by surge coupler. I had replaced original rusted brakes with galvanized new ones about 3 years before I sold boat and trailer. They were still in good shape. Of course I had...

    Proper Wobble adjustment

    I am trying to figure out how to install or adjust wobble rollers on my trailer. Most of the boat load is on 15+ ft bunks and there are two wobble sets per each side towards the bow. I have added a self centering keel roller because I am having difficulty getting boat perfectly centered when...

    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...

    Extension needed

    I have a 14000 lb triple axle trailer that is difficult to launch boat because I can't back trailer and boat into water without dangerously come too close at submerging the rear of my truck. I need a 3"x5" x 5' piece of galvanize channel to replace the 18" channel that came with trailer. My...

    Tying Down Large Boats

    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...

    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...
