    Losing speed around 3k RPM

    I took the boat out for a long run up the river. I was able to get on plane several times and usually cruise around 3k RPM. At the end of the day, I headed back down the river and when I raised the RPM to about 2800 RPM, the RPM shot up a bit and my speed dropped off. If I slowed it down to 2000...

    Carb throttle bent (brand new)

    I drove 40 miles out to the boat today to swap my 2 barrel Mercarb. I just got done removing the old one off my engine (needs another cleaning and rebuild). I thought I’d save time this year and mount a brand new carb until I get some time to clean the old one again. I pulled the new one out of...

    Identify these wires

    Hello, I am trying to identify what these wires are for and whether or not they should be connected somewhere. One is back by the distributor coming out of the wiring harness and has a ring connector. The other is by the thermostat housing and has a slip connector. Please look at the pics...

    Floscan gauge odd behavior

    When I turn the ignition key to the ON position with engine not running, the Floscan gauge needle goes crazy and flutters between zero and pegging. The needle really pegs hard too and you can hear it when it hits the stop at maximum. Any ideas on how to troubleshoot this? The actual fuel flow...

    Steering Play

    I have a rack and pinion helm. The system also has a power steering pump that assists with the steering. The outdrive itself is tight. However, there is some play that is observed at the steering wheel. I shot a video of me moving the steering wheel back and forth within the range of play that...

    Broken bolt on upper stern drive cover

    I was getting some work done on my stern drive and the technician broke one of the stainless bolts in the top cover. Just wondering if you have ever seen this issue before and if there’s been success getting it out. Thanks, Brian

    Shift shaft seal leak

    Hi All, The marina that stores my boat in the winter, just sent me an email telling me I have shift shaft seal leak and oil dripping on the floor under the drive. They sent me an estimate for the repair dated from November. This is the first I’m hearing about this now, which I think is weird by...

    Fuel Shutoff Valve

    I was thinking of installing a fuel shutoff valve so I can run the carb dry. Which section of the line is the best place to install a valve? I have a Mercarb and the original mechanical fuel pump. ​I'm trying to prevent having to rebuild my carb every year. Last year I used Stabil in the gas...

    I found these...

    Does anyone know what these are for? I found 2 of them laying in the cabin of my Sea Ray 215 in the under sink storage compartment. They weren't attached to anything, but they look important.

    Exhaust shutters

    How hard is it to get to the exhaust shutters? I know they are in the tops of the Y pipe. I'm guessing the rubber coupler will be stuck to the metal pretty good. Is there a good tip or strategy for getting in there without tearing the rubber?

    Idle and acceleration issue

    A little bit of background: I was having an issue with my engine not being able to idle last year. I did a complete carb rebuild last year and I also did an initial tune up (plugs, wires, cap, rotor, ignition coil). After the carb rebuild, I had the boat out on the water last fall (warm 60...

    Anode stuck in cav plate

    I got all the anodes off my Alpha 1 Gen 2 except the round one in the cavitation plate. The bolt came out no problem, but the anode itself is pretty stuck in there. Are there any tricks I could try to get it loose. I already tried the socket extension with a hammer on the bolt head going down...

    2 barrel Carb Fuel Line

    Hello, ​I am working on the fuel line that goes from the pump to my carburetor. What it is the factory fuel line made of? Is it stainless steel? ​One of the threaded fittings on my line has damaged threads and I'm trying to decide between two options: 1. Replace the fitting and re-flare the...

    Carb Replacement Questions

    I'm looking into replacing my carb, and I came across a carb that says it replaces the Mercarb part number 3310-864943A01 This one says it is a 2 barrel for the 1998 and newer 5.7L. From that description, I am assuming this carb won't work on my 1997 5.7L. Has anyone used this on a pre-1998...

    Exhaust manifold cooling hose leaking by hose clamp

    I am seeing water leaking out of the cooling hose right where it is clamped to the fitting on the bottom of the exhaust manifolds. This happens on both sides. I tried tightening the hose clamps more, but water still seems to leak there. Should I put some kind of gasket sealer where the hose...

    Engine will not idle after a good run

    I am experiencing a strange issue with my engine. I took the boat out yesterday evening for a run up the river. The engine seemed to run fine. I was able to get on plane and ran for many miles without any issues. When I came back to the marina and as I approached the harbor entrance, I of...

    Is there a way to check the hours

    I was wondering if there is any way to check how many hours are on my engine. Also, do you have a recommendation for adding an hour meter. My engine is in my signature. Thanks!

    Outboard as backup

    Does anyone recommend carrying an outboard motor on an I/O boat as backup propulsion in case the main engine won't run for some reason? I was curious if a small outboard or possibly a Torqeedo 1003 electric motor would be good enough to limp back to shore. I mostly boat on rivers where I can...
