    Weird. Got little hot. Then normal. Checked t-stat now won't crank from key.

    Went out today for a few hours. Boat ran great. While I was cursing at about 3800 RPMs I looked down at the gauges and temp was at about 180. It usually sits around 140-150 as I'm pretty sure there's a 140 t-stat in it. So I go to idle and the temp comes back down to normal in about 1-2...

    Spun or slipping prop?

    I have a 5.7 OMC with the Cobra drive. The prop I have on there now is an aluminum 15.5 x 15P. Pretty sure its the wrong prop but have been working out some quirks with the engine first. I read on here about putting a mark on the hub and prop and seeing if it is spun. Today I went for a 30...

    Might have finally got the egine squared away now the outdrive?

    Ok today I was out test driving after installing a new coil. Think (hoping) I got the engine squared away as it ran like a champ today. Well the trim is sucking a lot of power and making the outdrive faulter at higher RPMs, so I was messing with the trim today in the middle of the bay and...

    I can feel it. Im close. Still bogging, coil hot, wires to coil hot.

    So I was having some problems with my new engine running good then all of a sudden backfiring and not wanting to go over 3K RPMs. Even when it was running good it would bogg 90% of the time when the secondaries opened. Well, I pumped all of the fuel out of the tank and cleaned it, took the...

    Why remove meetering rods when removing carb air horn?

    I removed the air horn on my 1409 to check the float levels. I unhooked the connections, then I took the screws out and carefully lifted the air horn up. I checked to make sure nothing fell into the intake and nothing dropped off of the carb because this is the first time I have messed with a...

    How do these spark plugs look?

    Sorry if for the blurryness but it was a PITA to try to get my Iphone 4's camera to focus on the plug. How do these look? What is the preferred plug for the 5.7 OMC engine? These are what came in the engine when I bought it. They are Autolite 25. As always, thanks
