    Is Mercruiser 3.0L 4 cyl a good engine....compared to 470?

    1994 Mariner 115 HP reliability

    Before I had a smart phone with internet, I bought a bow rider with a Mercrusier 470/3.7L inboard/outboard. It was only after I bought the damned boat and started having problems that I googled and found iboats and the myriad warnings about that particular engine. I pulled the engine...

    MCM 165/3.7L/470 steaming near #4 cylinder upon cold start up (video)

    Re: MCM 165/3.7L/470 steaming near #4 cylinder upon cold start up (video) On thing I noticed about the gasket mating surface of the exhaust manifold is that it's not perfectly flat. I took a large file and started to clean up the surface when I noticed a sunken spot indicated by the grey area...

    Re: MCM 165/3.7L/470 steaming near #4 cylinder upon cold start up (video) Here's my pressure tester. Got all the hoses, plugs, and fittings at Lowes. No bubbles, except for a tiny one coming from the gasket every 60 seconds or so. Got visual ID on that one. It's held 15 psi for almost...

    Looking to make a homemade cooling system pressure tester, need ideas

    Re: Looking to make a homemade cooling system pressure tester, need ideas Here it is installed and pumped up. I put some Vasoline on the rubber disc to make sure it didn't deform when I put the cap on. I didn't go past the locking tabs on the reservoir neck, so that held it tightly in place...

    Looking to make a homemade cooling system pressure tester, need ideas

    Yesterday, after spending a couple weeks rebuilding my controller and hopefully successfully adjusting my shift cables and interrupter, I started the engine for the first time in about three weeks. Thanks to a Pertronix/Flame Thrower/new spark plug wire upgrade, it jumped to life and idled...

    ideal running condition merc 470

    Re: ideal running condition merc 470 Mine never goes past 160 degrees, even during very hot summers pulling lazy, thankless children on a two-person tube. My oil pressure will be up around 80 psi (according to my gauge) at higher RPMs. At idle, it's pretty much registering nada. Here's the TSB...

    Merc 470 Rebuild, issue with cooling system

    Re: Merc 470 Rebuild, issue with cooling system Could an exhaust shutter back up the water enough to allow it to fill up the exhaust riser and spill down into the exhaust manifold and then into the cylinders?

    MCM 165/3.7L/470 steaming near #4 cylinder upon cold start up (video)

    As some of you regulars know, I'm on my second season on a completely rebuilt 470. I'm not having any performance issues. In fact, I'm very pleased with how the engine performs. I used only OEM Quicksilver gaskets and other engine parts when not NLA. One potentially disconcerting thing I've...

    Installation of trolling motor on 17' Four Winns Horizon Fish and Ski: DONE!

    Mounting a trolling motor on my bowrider was tricky because of the slopping, curvy gunhale and the railing there upon. The only flat spot on the bow gunwale was where the running lights are. So, this was going to require relocating the lights further forward and down a step. I cut a 6"...

    MCM 165/3.7L/470 idling issues

    As some of you know, I bought this boat a couple of years ago and rebuilt the engine and outdrive. I'm at the point to where I'm giving attention to more minor things like voltmeter not working (needed some super glue on magnet that kept slipping off shaft), lights not working (broken wire)...

    Put Pertronix on a 470 today. Rotor won't slide down all the way.

    I'm a busy bee today. Decided to go ahead and install that Pertronix kit I bought 15 months ago. After installing the magnetic sleeve, the rotor sits about 0.15" inches too high and I can't get the distributor cap on. I rotated the sleeve until it was lined up, then pushed down firmly on it...

    need some tutelage on how electric choke, 3-wire alternator, and coil interact, 470

    In one of my other posts regarding my alternator not charging, someone mentioned that during cold starts, an extra amount of voltage is sent to the coil so the spark is nice and hot. I'm not sure if my wiring is correctly installed (clipped and capped off wires) or if my electric choke is even...

    470 shift interrupter question

    Last season, I read the sticky regarding this topic and meticulously followed the Merc manual's adjustment procedures several times on how to adjust the cables. I recall that it wouldn't even shift into forward (or was it reverse) as a result. So, I just did what it took with the adjusting...
