    Info on Mercruiser 0A494867 170Hp engine.

    Sure there are many, but it won't be a direct swap. Mercruiser also used Chevy and Ford engines but they were mostly V6 or V8 Engines. Your engine only has one front engine mount, the V engines will have two. The 4.3 Chevy would be the best swap to go to, they use the same gear ratio in the...

    Low Engine Temp??

    No. There should be no issues changing to the 140. There are no different specifications in Manual 2 for closed cooling or freshwater cooled as far as timing, point gap, dwell or carb settings. If your engine has issues running, it won't be due to the lower thermostat setting.

    Merccruiser taking on water.

    The exhaust bellows is below the water line/ Every time you shut off the engine it is full of water. If it has a crack in it, it would not enter the boat from there.

    Coil is getting hot 3.0 Mercruiser

    I think you were not suppose to remove the resistance wire. Ballast resistor and resistance wire are the same thing.... If you read the instructions, it says if your ignition system presently is equipped with a resistor/wire, do not remove it...

    There are a couple of known issues with the 470 engine. I have the last version the 3.7LX which was last made in '89. They have a large bore and torque along with very good fuel economy. Here is a thread on one of the issues...

    Losing Power - After two hours

    Get a temporary fuel pressure gauge inline between the fuel pump and carb inlet and run it. See if pressure changes when you have an issue.

    Back from long hiatus boating....

    Hello all! I've put the boat on the back burner for a few years unintentionally, but that's what happens when you let work take over. This year I decided to get it back in the water and have been working on it steadily. Man, boats don't like to sit that's for sure, but the electronics that are...

    In that video, he tells you how much play in the cable is allowed for both the lower cable and the one to the shifter. Did you measure how much play is in your cables?

    How to put lower unti in fwd? ( Alpha 1 gen 1)

    Turning the shift shaft CW, and rotate the prop CCW will lock it in forward. It has to be held there the entire time it is mated to the bell housing. If you pull hard enough, it will move the input shaft on the upper, but your fighting the friction of the impeller in the drive which makes it...

    ‘85 190hp 3.7L blown head gasket

    Yes you can switch to the aluminum version, that's what I have. You also have to replace the riser/exhaust elbow/reservoir if you switch to Al. They are different. I replaced mine probably 15+ years ago, they where a lot cheaper back then.
