    Mercruiser 3.0l Cylinder Head Interchange.

    I am in need of a replacement head for my 1993 3.0l cylinder head, casting number 14096620. I am having a hard time finding the exact same casting number. I have found a head from a 1999 model 3.0l on craigslist, I am unsure of the casting number right now. Does anyone know of any other...

    Alpha One Gen 2 Gear Ratio Questions

    So I recently purchased a 20' cuddy cabin boat with a 3.0l engine. I believe it is a 1993 model. The outdrive was stolen from the boat, and the boat has been sitting for about 5 years or so. I have a parts boat with a 4.3l engine in it, and what I assume to be a 1.81 gear ratio of a similar...

    Advice on installing outboard engine on old pontoon

    About 3 years ago I rebuilt a 24 foot pontoon boat for a family member, from the pontoons up. It was an old (70s maybe) pontoon that had been sitting in the woods uncovered for 20 years or so. There was no motor on the boat, so I did nothing as far as steering/wiring/enging. The boat had an...

    Installing complete outboard/steering/controls on older pontoon boat

    So I am rebuilding an old pontoon for a family member of mine. I've finished the decking and furniture now. When I got the boat there was no engine/wiring and only a console on some rotted deck wood. The steering wheel didn't have a modern style steering cable, instead it had 2 small cables...

    Water coming from rear of engine, torque converter area

    So we bought a boat that was missing the outdrive (supposedly stolen), its about a 95-96 model wellcraft with a 3.0l engine and alpha one outdrive. It was said to run good, just someone stole the outdrive. I just put a good outdrive on it from another boat we had that had a cracked block. I...

    Difference in out drives between 5.7l and 3.0l?

    I've got two boats here, both mid to late 90s models, and both have mercruiser engines and out drives. The boat with a 5.7l has a hole in the block, and the boat with the 3.0l had te out drive stolen. The out drives look identical, would I be able to just unbolt the out drive from the 5.7l...

    Bad powerpack/coil?

    I believe it is a 1989 Evinrude 40hp. Was running down the lake great, and within about 20-30 minutes of running, the boat just died. It would start right back up, but as soon as you gave it any throttle (I would say above 1000 RPMs) it would start cutting out and die if you didn't back off...

    So our block cracked over the winter....

    Its a 1996 Century Arabian 24 with a 350 Mercruiser and alpha one outdrive. We were kind of planning to pull the engine out anyway and beef it up a little bit, and now when we started it we noticed water dripping out of the right side of the block just below the head. My question is, will a...

    Can anyone tell me the year of my 40hp evinrude?

    I knew at one time, but have since forgotten. There was a sticker on the side of the engine with the model number, but it peeled off and i cannot find it. Is there a stamp somewhere else to look for? The previous owner painted the engine white so you cant see much on the outside. Its a '87-89...

    Needing some info on my pontoon I just got!

    Just did some trading, and got a 1996 Godfrey Marine Aqua Patio 240PE. The boat has a 3.0 I/o engine, which seems to be fairly rare, I cannot find much info online about this boat, all of them I find seem to have outboard engines on them. Anyway, I assume the engine is a 4 cyl. chevy engine...

    2000 Yamaha GP800 top speed?

    Can anyone tell me roughly what the top speed should be on one of these? Took mine out for the first time yesterday and couldnt get about 38 mph. I was reading the specs on my GP760 and seen a top speed of around 55-58, so i was expecting far more than 38 mph out of the 800.

    First time PWC Owner questions...

    So today I bought my first pair of wave runners. One it a 2000 Yamaha GP760 and the other is a 2000 Yamaha GP800. Both have been sitting over a year when I bought them. I brought them home, added some fuel treatment to the tanks, and jumped them off my truck and they fired right up and ran...

    5.7L Merc 1995 randomly wont start

    We got out boat (1995 Century Arabian 240) ready to go to the lake about 2 weeks ago, ran the boat and everything seemed fine. We ended up not going, and when we went to start the boat last weekend it would crank but never fire. Its getting plenty of fuel into the carb, kill switch was on. At...

    Question about changing engines and outdrives in a boat

    Im looking at a project (1988 Baja) with no motor or outdrive. I would believe the boat either had a 454 or 350 engine in it. Ive got a mercruiser 305 that is about a mid 70's to mid 80's laying around that runs great with the outdrive. Would it be feasable to put the 305 into the Baja...

    Mercruiser 898 lower unit shifting problems

    I recently changed the impeller in my mercruiser 898. It shifted/sounded fine before I touched anything. Now the lower unit doesnt want to stay in a gear. When I turn the shift rod by hand (with the lower unit off) It will lock into a gear (I can tell by which way the prop wont/will spin)...

    Mercury cooling system question

    I have a 1987 mercury 80hp oil injected engine. Ive had the boat for about a year, and used it about a dozen times or so at the lake. Ive never had any problems with the boat over heating or anything. Should I be seeing a stream of water shooting out from the upper half of the engine? Ive...

    Question about reinstalling lower unit

    I have the lower unit off of my 1987 Mercury 80hp outboard to put some new gasket in. When I removed the lower unit, it had a silicone seal inbetween the lower unit and upper unit. Is this seal really needed? I have about a 1980 Mercruiser 898 inboard and when I worked on the lower unit of...

    Has anybody ever...

    Added a double deck to the top of their pontoon? It seems fairly easy to do as long as you had some aluminum bracing and someone to weld it. Thinking about adding a 8x8 deck to the top of my 20' pontoon.

    Need help with oil leak on 1987 Mercury 80hp 2stroke

    I noticed the oil was leaking from the water intake on the side of my motor, so I did some research and found a bad shift shaft seal would cause this. So I ordered a new seal and replaced it. I noticed the old seal looked to be perfect, no cracks or holes, but I replaced it anyway. The motor...

Everything seems to be going great, but when im cruising on the lake I have water coming up through the deck and soaking the carpet. I did not really seal the seams much other than just...
