    Holley Dual Feed Fuel Rail/Log Question

    I have the fuel line shown by Scott from the pump to the fuel rail but the way it lays out you can see (pic above) where the end of the fuel line from the pump is right at the coolant hose so it isn't flexible to get around that hose causing the fuel rail to need to be lower than the coolant...

    Holley Dual Feed Fuel Rail/Log Question

    My Holley carb has a rigid dual feed fuel line. I have had to bend the arms down a bit so that the inbound fuel line clears the cooling hose from the TStat with a carb spacer in place. I have heard that these rigid feeds are prone to leakage. Is there a better option in the way of a marine...

    How to Switch to Antifreeze Cooled Engine

    A potential problem (voice of experience based upon my Mercruiser Alpha One) making the switch to closed cooling could involve changing the exhaust pipes as well as the manifolds as the angles and position of the exhaust might change. Just a heads up....

    Alpha One Gimbal Ring Hinge Repair?

    They did a great job. I use the alumaprep and alodine method followed by epoxy primer and urethane topcoat.

    Alpha One Gimbal Ring Hinge Repair?

    I went ahead and had the hinge built up with TIG welding at a machine shop. Here is their repair work picture. Peace of mind, $62.00.

    Gimbal Housing Part Numbers

    As a follow up, I received a very nice used gimbal housing casting number 42259-C with the 5 hole exhaust mount. I have checked it as closely as I can against my original 42259 (with no suffix) and it appears that the only difference is the additional bolt hole at the top for the 5 bolt pattern...

    Constant alarm but motor running fine - 2004 5.7l raw water cooled Thunderbolt

    Either low oil pressure or bad oil pressure switch would be my guess since it stops when increasing RPM's. I believe the oil pressure switch would be normally closed (alarm on) when you first start and then open up with increasing pressure to turn off the alarm as the engine fires. It should...

    Question about resin

    I used epoxy for the structural work on my intermediate hardtop (the one between the upper and lower windshields in my profile pic) and for ribs in my upper hardtop for the strength. That wood (marine plywood) will all be covered with headliner so I don't have to "stick" anything else to it...

    Gelcoat Application Questions

    Thanks. Sounds like a plan. I have one of those same guns. Did you use Duratec on all coats or just the finish coat?

    Gelcoat Application Questions

    I am not the best painter in the world so am concerned about runs in the vertical surface of the transom with spray. I have a gravity feed gun with large nozzle for gelcoat though. When it comes to the bottom, what kind of gun do you use to spray up from the bottom? I don't have a pressure...

    Part Identification.-

    If you are just looking at the piece at the end, it is a shift slide and I think the Mercruiser part number is 8507522.

    Alpha One Gimbal Ring Hinge Repair?

    I just got a used gimbal housing that fits the Y pipe I need. The hinge at the base of the gimbal housing has some damage at the ring pivot hinge. It looks like someone ground it away a bit to get the lower pin out. Do you think it will be ok or should I have the spot TIG welded to build it...

    Gelcoat Application Questions

    I have three different areas that I need to apply gelcoat over the old gelcoat, Deck/Hardtop, Vertical Transom, and Bottom. I expect to spray the gelcoat on the Deck/Hardtop since they are flat horizontal surfaces for the most part. The questions I have are on the other two surfaces. Vertical...

    4.3 engine mounted raw water pump inquiry

    This may be an invalid thought but would both pumps in a Y configuration give you a "backup" water flow if one fails? That is, if the impellor in the seawater pump fails, the lower unit pump continues to cool the engine at least somewhat and vice/versa? Just a thought to ponder.

    4.3 engine mounted raw water pump inquiry

    After a lot of research, I decided to go with a Y connection for seawater with one leg of the Y for a seawater pick up outlet as primary flow for the Seawater Pump and the other leg for the Alpha One internal pump outlet. Both are providing flow to the system in normal operation. I am running...

    Repair Y Pipe Possible?

    I ended up getting another used Y pipe and it should be here in about a week. I also bought another used gimbal housing that has the 5 bolt pattern so I can correctly bolt the Y pipe with the 4 hole in line bolts. The gimbal housing will also be here in about a week. I did post a thread on...
