@Djoub, Glad to see that you are tracking down your fuel feed issue. One thing I do notice, the red plugs in the bungs for the crossover connection look suspect to me. I would consider either replacing them with threaded aluminum bung plugs or install the shut off valves and crossover hose. The...

I have been operating our MS 390 for ten seasons and have the same issue, not sure if there is a "cure". With the fuel transfer valve(s) open, fuel is going to flow to the heavier side of the boat even if it is only off balance a minor amount. First tip is to fill all tanks (fuel and water) and...

You may all want to laugh but I got one of these hose out my small fishing skiff, it works great (within its limits). Drop the pick up hose in the water and pull the trigger, works as promised. Also great for cleaning the bilge in the big boat, 300 PSI but not a lot of volume, gets into the...

Morning, your parallel (1-2) switch may be bad, but i suspect one of the circuits in your line 2 section has an issue. If you turn off all of the circuit breakers on line two does the parallel switch still switch off? if so I suspect the switch, If not it is probably a circuit on line 2. With...

I have owned mine (390) for ten years and have never seen a shut off to the transom mounted shower if that is what you are referring to. If you find one please post its location! Access is very limited in that area of the boat, you would probably need to cut a hole in the transom storage...

In the past on a boat with aggressive diamond pattern nonskid (Tiara) i have used a generous amount of inexpensive cleaner wax to clean/treat the surface. The solvent in the wax dissolves the black spots. Pour on a generous amount and work into the non skid with a stiff short bristle brush in a...

Hi Jay, PDF's attached, if they do not come through PM me, thanks and good luck, Gary

Hi Jay, if i remember correctly from when I had mine done, the compartments are divided by the trim tab actuator locations. If you look from the bottom the tab rams are in pockets, these pockets create the divisions. The real purpose for the access plates being cut into the swim platform lid is...

Morning SeeVee, do you know the rotation and shaft size? I have freshly reconditioned RH Nibral four blade (super cup?) I think it is 24" x 27P with a 1-3/4 tapered shaft fitting. It is in my boathouse, if you have any interest, I can go get the exact specifications.

Good News! finally got to the boat this weekend and the manufacturers emblem is still in my upper venture windshield. Info: Viplex Corp. Melbourne Florida. Hope this helps.

You may want to try Greatlakesskipper. It is a clearing house for boat manufacturers over run items and equipment. I looked on their site and they have a number of table tops and pedestals. You would need to assemble the parts but it sounds like you have that covered, happy shopping! P.S. There...

I think my original venture windshield has a manufacturers decal on it (2000) Model Year 390. I will look at it this weekend and report back. I want to say it is made by Taylor.

Morning, look at the top of the swim platform. If there are two inspection ports above the trim tab cylinders, the platform has been repaired per the Mainship repair procedure. If there are no ports, I would assume that the repairs were not performed and the foam flotation may be saturated, this...

Hi Benthic2, in reply to Originally Posted by Noahstvr .... They have a very square stern and a lot of buoyancy due to the foam (or after recall, hollow) swim platform hull extension. .... This vintage 350/390 Mainships were built with the swimplatform/hull extension filled with foam. The...

Hi Shrew, We have the same boat (300 Cat power) and similar handling. Quartering stern seas are the worst in these boats. Square on the stern is a little better but defiantly the worst trait of this boat. They have a very square stern and a lot of buoyancy due to the foam (or after recall...
