    1976 Mecruiser 351W Ignition System

    Hopefully your ring gear is not damaged where you will need to remove the engine to replace it. What you need is a replacement starter. The Prestolite starter with the Bendix drive system has a tendency to chew up ring gears. The replacement starter is of the “Dyer “ style drive gear...

    290sp square trim gauge issues

    Great picture. My son says that the only measuring device Volvo designers have is a framing square.

    290sp square trim gauge issues

    Scott you are right but I always liked to aggravate the Volvo people about the square gauge. I never could get an answer as to why it was square. Merry Christmas and a Happy new Year!

    290sp square trim gauge issues

    I Re powered several boats with the square trim gauge, I kept asking for the square hole saw tool that was needed but never got an answer back. My local Volvo service rep told me that whoever designed that gauge must have also the been same person who designed pin ball machines! Merry Christmas...

    Engine removal thoughts

    Whichever way you get the engine out you really need to have it on an engine stand. Trying to replace the sheet metal on an swinging engine is no fun.

    Engine removal thoughts

    Put the hoist in the back of a pick up truck, strap it down with ratchet straps. Also remove the wheels off the boat trailer which will give even more working room. After the engine is clear of the boat the hoist may not go down enough to mount the engine on an engine stand. You will just...

    Power Trim Control Panel

    I have to agree with Scott. Most likely the control was up graded in the past.

    Power Trim Control Panel

    Probably the lower toggle switch was the trim control which was wired through the trim limit switch on the gimbal housing. The top button is probably the trailer button for full tilt. Sylvan probably cut corners and did not use the genuine Mercruiser control that has the trim/tilt controls on...

    Volvo Penta AQ131A & 275 OutDrive

    There are 2 areas on the drive that could be the problem. The hose fitting mounted on the suspension fork will rot off allowing air to get into the water stream. The other is the “O” ring that seals the lower gear case to the mid section allowing air in also. Sierra # 18-2777 Or Volvo#...

    What is this?

    Definitely a MPI model engine that was connected to a stern drive. Probably in the 430 HP range. Looks like the model of engine that was in the Donzi I had.

    New Carb conversion issues 5.7

    Do you think that there is a restriction between the fuel pump and the suction tube in the tank? Were you having a fuel starvation problem before removing the fuel injection?

    New Carb conversion issues 5.7

    With the engine running what is the voltage at the + or bat side of the coil? How much fuel pressure is at the carburetor?

    Raw water pum

    Try setting up a bucket of water in the boat with the suction hose directly in the bucket. Or just plug in a garden hose to the suction side to see if it will pump the water.

    Excess vertical play in intermediate shift shaft? Alpha1G1

    There is supposed to be a stainless flat washer on the top of the shift shaft bushing. This washer holds the brass intermediate shaft up so that it stays engaged in the bottom of receiver under the bellhousing. You will have to drop the lower to add the washer.

    Mercruiser 5.7L warm start challenges

    How many idle mixture screws does it have? The Rochesters have 2 and the Mercarbs have 1. Personally I never cared for the Mercarb.

    Mercruiser 5.7L warm start challenges

    Before re-starting the hot engine remove the flame arrestor and look if the choke is closed and as SD suggested look down the air horn to look for fuel leaking. Also connect a volt meter to the + or bat side of the coil to measure the voltage when the starter is engaged. There should be full...

    Ford 302 pinging

    All 188s came only with Holley carburetors. Someone may have taken the adapter from a 233 which only came with Rodchesters atop the Holley pattern adapter that mounted the Rodchester.

    What do I check next on overheating issue?

    If every thing suggested checks out then you probably have a case of “Bravoitis”. This is a phrase that the Donzi and other sport boat owners call it. From the age of your drive you may be getting exhaust gasses if your exhaust exits through the drive. Also there may be a foreign object in the...

    Ford 302 pinging

    The anti siphon valves are threaded into the 90* elbow on top of the tank fuel outlet. Have you ever checked to see if there is a small cylindrical filter inside the tube that goes into the tank? There is a good chance that there is one, you need to remove the tube and make sure to remove it.
