    mercuiser 3.0 ignition issues. Help!

    OK. SO the last time I used the boat was last year and I had to get towed back to the dock. I have been fighting an ignition issue with this thing forever. Boat starts and runs great until it gets hot and you shut it off. Then it wont restart. So I took out a buddy with the goal of figuring this...

    Mercruiser aplha one gen one bent prop shaft

    I have a alpha one gen one outdrive with a bent prop shaft. It is about 40 thousands off at the tip of the threads. It has been that way since I got the boat and have been running it like that. It may have been run like that for a long time, I don't know. Doing some reading it sounds like...

    Home prop repair questions

    So far this year I have been lucky enough to come in contact with 2 submerged prop killers. The first one bent over 2 of the 4 blade tips, but other than that was ok. One of them I was able to flatten back out, but the other broke off when bending it back. About 1/4 inch of the very tip is now...

    Alpha 1 Gen 1 Water drain hole plugged

    I have an Alpha 1 Gen 1 drive and I am pretty sure the water drain is plugged. I have been working a wire in it and a bunch of sand has been coming out but it still seems plugged. I am guessing that the passage goes up from the drain hole. I get in a little ways and then it stops. Some water...

    3.0L prop help... Again

    I have a 1983 Sea Sprite 780 XL 17' boat with a 3.0L mercruiser and a Alpha 1 Gen 1 drive. When I got the boat it had a damaged but useable 15x15 3 blade prop on it. Since it was damaged I came on here looking for advise on what prop to get. Unfortunately the tach was off when I was giving my...

    Water pump issue? 3.0L Alpha1 Gen1

    I recently replaced the water pump on my alpha1 gen 1 drive. I watched a bunch of videos while doing it and noticed that when I run mine on the muffs that I don't have nearly as much water coming out the prop as others. When I run it I get a little spray out of the exhaust prop, and then a bunch...

    Alpha 1 Gen 1 Shift issues after water pump replacement

    I recently replaced the water pump in my Alpha 1 Gen 1 drive. Everything went back together just fine, but I noticed that when shifting to reverse it didn't see to be fully engaged. Forward is fine and engages solid. I adjusted the shift cable and got it better, but now I am worried something...

    alpha 1 gen 1 water pump replacement question

    I am replacing the entire water pump in my alpha 1 gen 1 out drive. Serial number starts with 631. I have it all disassembled and it is a good thing I am doing this. It is badly worn, pieces missing and has melted at one time. One thing I am seeing is that the top cover of the pump on mine has a...

    3.0L Warm starting issues

    I posted this once before but it looks like it has disappeared with the issues they have been having. I have a 1983 3.0L, serial number starting with 497. I have replaced all of the ignition components, ground all of the valves and verified good compression. It seems to be running good, and...

    mercruiser 3.0l alternator question

    I have a 1983 mercruiser 3.0l serial number 4524932. The alternator doesn't seem to be doing anything. Battery voltage is the same with engine running or not and at any rpm. I looked in the service manual and from what I am seeing this isn't a stock alternator. There is the output wire, and then...

    Prop Question

    Re: Prop Question here are a couple pictures of the prop and one of the boat. It does sit pretty high in the water, but I will try to get to the foam and see if it has water in it. Being a 15" diameter does that possibly have anything to do with the lower rpms? Seems like the largest diameter...

    Prop Question

    I have a 1983 Mercruiser 3.0l with the Alpha1 gen1 drive on a 17ft Sea Sprite ski boat. The prop that is on it right now is a 15x15 and is pretty beat up. I just got this boat and took it out yesterday. It seems like it comes out of the hole pretty good and planes out quickly. The max rpm at WOT...

    1983 3.0l w/alpha 1 service manual

    Can any one tell me where to find the service manual for my 1983 3.0l engine? All of the post say to go to the adults only section, but I can not find it for the life of me. I have searched for it other places online as well and have came up empty. Thanks in advance.
