    5.0L Alpha One Gen 2 Trim electrical question

    Last trip out my trim suddenly stopped working. No clicks in either direction. I did hit the down button while reversing fairly hard so I am thinking I just opened the 110A fuse but I also wanted to take a "spare" for the 20A inline control fuse. I have Google hunted and searched the archives...

    Ignition circuit fuse blowing

    I am having an issue with blowing the "ignition" fuse in a 2003 Caravelle with the Mercruiser5.0MPI. I replace the fuse and the boat runs fine for an hour or two and the fuse blows again. Checked the obvious (loose or pinched connections under dash, engine comaprtment etc). The fuse blows...

    Wiring Diagrams

    I am having an issue with blowing the "ignition" fuse in a 2003 Caravelle with the Mercruiser5.0MPI. I have the Merc Service manuals which show the enginer and trim wiring harnesses but I am looking to find the wiring diagrams for the rest of the boat. It seems Caravelle went out of business...

    Captains Call Exhaust

    Can anyone tell me if there is a true performance improvement when running in Thru-Hull or is this feature just for "show" or I guess for "hear" in this case.

    2003 Merc 5.0MPI Alpha One

    I have spent some time searching EBay etc for a real Merc Service manual for the drive in my New boat to no avail. Anyone know where to get one?? The Merc owners manual that came with the boat (the original owner had all of the manuals that came when he purchased the boat new) is useless...

    Single Point Drain on Merc Alpha One

    Well, as some of you know I had a 88 Bayliner with a 5.0 OMC for 23 years which I swapped engines in and knew very well inside and out. This month I ran across a newer boat and decided to upgrade. It is a 2003 Caravelle Interceptor with the Merc 5.0 MPI Alpha One. It has the Merc single point...

    Can some one please tell me the correct trim/tilt motor to replace the original for a 1988 OMC CObra 5.0??

    Source for Interior Upholstry to match original

    Where can I get the vynl on the seats. I have no idea where to get the same color pattern as the OEM stuff in there now. Most of mine is not in bad condition except the two seats next to the engine cover in the rear and the rear deck cover. These are fairly cracked. I hate to put in a couple...

    Saturated Foam??

    I have read many postings regarding foam and replacement, flooring etc but my question is more in a troubleshooting line. I have an 88 boat which has spent most of its life stored outdoors. Winterizing includes covering etc but none the less over the years water has on accasoin gotten inside...

    Got the boat running just in time to catch the latest increase

    Well guys, gas topped $4 a gallon here in Chicago today on the water. I got the boat running two weeks ago and I think they planned it just for this week end, to catch all us 4BBL V8 guys going out for what could be one of the last week ends of the boating season here. Last two week ends I...

    Question for veteran mechanics

    I just replaced the head gaskets on my 5.7. I burned a gasket for as yet, an undetermined reason (see the picture at the end of this posting). I asked many for ideas why this might happen and one veteran speed shop guy said he had seen this happen due to a crack (not visible) in a head bolt...

    Advice on removing manifolds/heads

    I would like to know from some of the guys who own boat repair facilities where time is an issue for repair, what you do to remove the old gaskets. I just pulled my heads to repair a blown head gasket and when I went to reinstall it took me over 2 to 3 hours to clean off the old intake, exhaust...

    Question about exhaust flappers

    While I had the exhaust system off to pull the heads I double checked to see if the flappers are still there and functioning OK. They both are in good condition and seem to rotate freely but I did notice that the holes in the "Y" pipe that the shaft go through seem to be worn pretty badly. I...

    Should I pull both heads??

    I am looking for opinions as to what can cause a head gasket to burn through to the adjacent cylinder right under the head bolt. There was definately no overheating or even a niticable loos in power when it happened. Running WOT for maybe two minutes and when I slowed up ti idle the engine was...

    My 5.7 converted itself to a 4.3 today

    Well guys, back to the drawing board. Remember the post we had a wekk or so ago where we were all trying to decide which two cylinders of a 350 were cut off to make the 4.3. Today I found out it is 6 and 8. I was just cruising along a WOT at about 4500 rpm just fine. Came down to idle speed...
