    Has anyone installed trailer guides?

    How close do you guys position the PVC pipe from the rub rail? I ask because mine are like 4" away on either side and the damn boat always seems to rest on either the starboard or the port PVC leaving 8" on the other side. One bunk will be under the chine almost and the other in between the...

    Who on here knows how to tune a quadrajet?

    I have a 1992 Chaparral 2550sx with a 454. Serial OD717696 I I bought the boat a few years back knowing it had a Webber square-bore carburetor that had some warm start issues. I was surprised to see that the square-bore Webber was mounted on a spread-bore manifold. This is consistent with...

    High Idle After Overheat - 454 Mag Bravo Gen V

    There is a yellow hose between the fuel pump and carb right? Did you remember to hook it back up? Did any portion of that hose melt causing a vaccum leak?

    Where to pick up power for electric choke?

    Thank you as well. I think the back of my mando alternator has the AC tap. I need to verify with my multi-meter when the engine is both off and on. Thanks guys.

    Where to pick up power for electric choke?

    Thank you for answering. I sort of thought the same thing. Dont draw from the coil and dont hook up to the key but hook up to a spot that would give power only when the engine is running. With no wiring diagram but the one I attached to go off of I was more inclined to use the AC tap. I know...

    Where to pick up power for electric choke?

    So millions of boats use the purple wire? That's why I signed up to the forum, to ask questions I do not know. The PDFs are not pictures. The PDF's are pages from my mercrusier manual showing a purple wire go to the coil but not the choke. If the manual showed a purple wire going to a choke...

    1992 Chaparral 2550SX with the 7.4 and Bravo1 Engine SN: OD717696 I am removing a webber carburetor with a divorced choke and replacing it with a Rochester carburetor with an electric choke. Where do you guys like to pick up 12v to supply the choke? I think if I run a wire to the purple on...

    Does motor oil go bad if left in the pan for more than a season?

    I was performing some maintenance on the boat I picked up last winter and I could not recall if the previous owner said he changed the engine oil prior to selling it to me. It looked clean but I thought better to change. It is a 1992 Mercruiser 454 OD717696 which I found out takes 7 quarts...

    Which oil for fuel pump?

    Hello, I was doing a little maintainance on my 1992 Chaparral 2550SX with a 7.4 Mercruiser and I thought that I would also drain and refill the oil in my fuel pump. I could not find much information on the required oil. I have both sierra drive lube and 75w-90 gear oil in my garage. I am...
