    Mercruiser 5.0 MPI Won't get onto plane after Top end Rebuild

    Hello, this boat (2003 Sea Ray 240) ran fine this spring, until a pinhole rotted between the water jacket and the valve area in the head which made it hydrolock when we tried starting it after it sat for a few hours trickling in. So we replaced head gaskets, heads (new remans with the same...

    Mercruiser 5.0 MPI Hydrolocked

    Hello, thanks in advance to anyone that can help me out! Took the boat out two nights ago, it started at the dock no problem (I always start it when I get there just to be safe) we then hung out at dock for about 2 hours, went to go out and it was cranking pretty tough and made some harsh...

    5.0 MPI Engine Alarm Sounding

    I have a 2003 Sea Ray 240 Sundancer with the single Mercruiser 5.0 MPI. Let me start off by saying when it's running, it runs perfect. And that's about 95% of the time. I also did buy a Rinda scan tool and these are the codes that came up (I don't think they are linked to the issue) - Fault...

    Is this crack something to be concerned about?

    Hi there, I am looking at buying this boat it's a 2004 Four Winns 248 Vista. I went into the cabin below and at the center of the boat in the Aft cabin (under the captain's chair essentially in the middle of the boat on lower) I noticed this crack. I can't see anything on the outside. Is this...

    1985 Johnson 70 Plug unhooked at controls?

    Can someone tell me what this plug is for? I see the wire and plug that goes into this but it's been unplugged since I bought the boat. The plug has three prongs but only one is in use and it is purple. Thanks, Ryan

    Fiberglass Stern Damage, Just re-coat with Gel?

    I really don't want to talk about how this happened.. Happened today, I used the boat a few hours after and it didn't' seem to take on much water at all, but I'm not sure if using it like this will result in more damage or water to leak though? Any advice is greatly appreciated. Thank you!

    1976 Johnson 25 Stalls when given throttle

    Re: 1976 Johnson 25 Stalls when given throttle The roller is touching the throttle timing cam. The roller won't rest between those two lines either at full throttle or at no throttle in ANY gear. Here is a picture of where it is at no throttle. Here is a picture of the right side of the...

    1976 Johnson 25 Stalls when given throttle

    I have a 1976 Johnson 25 that I just got running recently. It didn't have spark before so I swapped all the electrical with electrical from a power-head with great spark. It will start right up 1st or second pull with the choke and after it idles for 10-20 seconds (or until a little warm) I...

    1976 Johnson 25 25RL76E

    Re: 1976 Johnson 25 25RL76E Thank you for clearing that up TX1961, I assumed it was something like that but wanted to make sure first. I'm attaching a few more images of me using an ohm meter at the spark plug coils. (I realized there is a driver coil under the flywheel too) Let me know what...

    Re: 1976 Johnson 25 25RL76E Please ignore the last attached image in the previous post. This is supposed to be the last image to go along with Unrelated to spark questions below: -Here is a picture of the thing that slides counter clockwise if I increase the throttle arm. It doesn't go far...

    1976 Johnson 25 25RL76E

    Re: 1976 Johnson 25 25RL76E Unfortunately I'm not ready to start it in a bucket.. I removed the spark plugs and the motor turns over smoothly but it does look a little dirty on the top of the pistons. The spark plugs were pretty wet. - I hooked up my spark tester and made sure I had it...

    1976 Johnson 25 25RL76E

    Hello, I just purchased this boat, trailer, and motor listed above together. The previous owner says it ran fine last summer but he hasn't had it in the water to run it lately. He says it may need a couple of plugs but he's not sure. AKA who knows.. The trailer may need some tires but...
