    Engine choice

    Prior rebuilder must have been ignorant, or ran out of money, or both. The block and heads were machined, the pistons were new, but the rings definitely did not belong in these pistons. The oil rings collapsed into the narrow grooves and allowed so much oil into the cylinders that I doubt the...

    Engine choice

    Thanks for your advise on the Mercruiser swap, I took it to heart and will do it on the Bayliner Ciera 2455 that I'm keeping. The other Ciera 2450 will get a 305 as well with a Cobra that I have plus the upper gears of another cobra I just bought for the purpose. Now I have the proper gears...

    Engine choice

    The gen 1 water pump is widely criticized online. However I would think that they are exaggerating if the actual life of the impeller and related parts are 3-5 years. They also say that the drives are near identical, so I gather that the Gen 2 robustness is in the gear set or in the shafts and...

    Engine choice

    Thx for the input guys. So I'd be better off with a gen 1, easier and cheaper. What's the story with the water pump, if it must be changed every season that's no problem, my outdrive comes off the boat every winter, so it won't get a cold, hehe.

    Engine choice

    I find myself lucky that the holes are the same, as the mercruiser units are readily available, unlike the OMC drives. What is the difference between alpha 1 and 2? these are the easier to find.

    Engine choice

    I've considered going Mercruiser, but I did not know the transom unit would be compatible with my cobra powered hull. If that is the case, I might go for it, using the Vortec I already have (after spending last winter re-fitting the connecting rods in their right positions, as they were mixed...

    This is the engine on the "new" boat

    Engine choice

    Perhaps a little history will add context to this story. I bought this Bayliner 2450 3 years ago, engine winter cracked, replaced the engine with a 5.7 vortec for which I bought a Edelbrock air intake, so I could fit the original quadrajet. The engine turned out to be flawed, prior owner...

    Engine choice

    I have a Bayliner 2450 hull that was originally setup for a 5.7 liter, but it came without engine or outdrive. I ran across a Cobra 2.3 drive and I wander what engine I could fit for that outdrive that will match the bellhousing on the hull and won't kill the gears of the drive. I know the GM...

    Mechanical to electric fuel pump

    I used an electrical fuel pump when I installed a carbureted 5.7 Vortec on my cruiser. It worked just fine. Too bad the engine did not perform well due to prior owner improper installation of custom connecting rods. I took his word and did not inspected the engine internals. It would idle...

    Mistery fuel line

    Perhaps you are trying to tell me that the pump has an inlet connected to the exhaust plate and one outlet that goes to the pisser. If that is the case, the other outlet on the back plate should be plugged, correct?

    Mistery fuel line

    Thanks bullet, that is interesting. So I should connect the mystery fitting to the pisser on the back of the motor? I have another fitting coming out of the rear plate, by the middle cylinder, looks like connects to the water jacket (is that what you refer to as Top fitting?) I thought that was...

    Mistery fuel line

    Need a little help here, I just put back together a 1980 (ish) merc 70 HP triple and I can't find a connection to one of the 4 fuel lines originating from the fuel pump. One intake line comes from the connector to the fuel tank, goes to the pump, from which another line goes out to the fuel...

    Force 50 HP needs the force

    I was also reading some posts about swapping to a Mercury CDM ignition, since I'm in for a new stator anyway, this may be another solution. However, the thread does not specify which engine they did the swap on. A pic of the coil plate shows 3 coils, so it must have been a triple cylinder...

    Force 50 HP needs the force

    I can only see one CDI, the darker blue box below the two coils, although the black coil has the marking that reads "CD", is this a dual CDI or single CDI ignition?
