    Engine Swap Feasability

    I have an excellent 1995 5.7 Mercruiser engine. I have been trying to match it up with a boat with a bad engine. I saw an ad for a 2004 CHAPPEREL with a VOLVO PENTA GXI 5.0 MOTOR with a cracked block. Would the 1995 block work in a 2004 boat? I know the 1995 did not have a knock sensor. Is...

    Swap a 350 small block into a 454 large block boat

    Hi, I saw a 1990 cobalt 252 for sale with no engine. The owner has a built up 454 he wants to keep, including the bell housing. The outdrive is a Bravo 1 which would come with the boat, as well as the transom plate. It has captain call exhaust set up. I have a 5.7 engine from 1995. Is it...

    Engine Swap on a Stingray boat

    I am looking at a purchase of a 1994 Stingray 20ft. boat that has a 4.3L V6 and an Alpha 1 outdrive. The owner described it as having water in the oil......a lot. Heads? Cracked block? I have a good 1995 5.7 vortec Mercruiser that I would swap out for the V6. Is this feasible? Does anyone...

    ALPHA 1 SHIFT SHAFT SEAL LEAKING........I think !

    I have been trying to locate a slow leak on my alpha 1 outdrive. (actually alpha 1 lower MC 1 upper). I could not find the leak with the upper and lower connected so I split them and did another pressure test on the lower. I found that the shift shaft seal leaks a lot if I push on the top of...

    Outdrive flunked pressure test

    1979 228 Mercruiser. Alpha 1 lower unit / MC1 upper. I replaced the water pump on my outdrive and re-assembled and did a pressure test. It leaks down to about 1 lb. over an hours time. I have done the soapy water test on the drain and vent plugs but not sure how to proceed. I did install...

    Do I really need to tear all this out?

    I found some rotted stringers in the motor mount part of the stern. We tore out the fiberglass around the wood stringers to replace. On the port side of the transom, where the stringer ran into the transom wood, the transom wood is rotted. I took the transom plate off and found the wood...

    shift shaft alignment on out drive .....maybe this is obvious, but not to me!

    MC #1 1979 228 mercruiser. I understand the lower shift shaft has to be in forward from the manual. I understand the intermediate has to be in forward, which is described as "straight ahead" to line up with the upper shift shaft which is also straight ahead to be in forward. It seems the...

    Transom Repair 1979 Century 3000

    My stringers were showing rot when I tried mounting engine mounts, so we cut into the fiberglass and found really rotted stringers. Checking the lower transom shows some rot also. A repair guy says we should replace the transom wood. He proposes to cut the last few inches of the beams and...

    Outdrive Identification

    I have what I think is a MC#1 upper unit married to an Alpha 1 Lower unit. The upper has the loop on the top #5209992. The Lower Unit has a number inside the casing in a cavity next to the shift rod #1623-8950-0 (last digit tough to read.. could be 6 or G). The anti cavitation plates are...

    First Time Impeller/Pump Replace a few small issues....

    1979 228 Mercruiser MC-I drive. I have taken apart the upper from the lower units. I notice there was no pin in the top of the drive shaft, and I thought there would be. If I was running without it, how would it affect performance and/or wear on the drive? Also, the shift tube hanging from...

    I have been working on my 1979 Century 3000 bowrider for quite a while now. I have been rehabing the outdrive, put an engine together for re-power and am ready to put the engine back in the boat. I was drilling some holes for front motor mounts and found water! A litte background. Some years...

    Confusing Torque Values for # 1 outdrive Bell Housing Hinge Pins

    I have read different torque values for the hinge pins on the bell housing for early pre-Alpha drives. I have seen 55ft-lb and 95ft-lb. I have a 1979 228 Mercruiser set up. The serial number on the back of the outdrive is gone. I am pretty sure it is a #1 drive Have the earlier recco...

    Gimbal Rings turns more Left than Right 1979 228 Mercruiser Pre-Alpha

    Sorry for the long post. I have been trying to figure out why my boat steers way more to the left than right. The outdrive is off, bell housing off, engine out. I disconnected the steering lever andfound the gimbal ring would turn more to the left than to the right. Even so, the steering...

    Fuel filter location

    I have a new Edelbrock 1409 carb on my 5.7 vortec longblock build. My old rochester carb had a small filter built into the carb at the fuel inlet. The Edelbrock has none. I do have a fuel filter/separator canister installed. Is this enough filtering? or should I install an inline filter...
