    Gimbal bearing came out with the drive shaft

    Pulled the motor from my 2nd parts boat to swap in the SC since it’s better… the outdrive didn’t come out so easy and when it did come out, the gimbal bearing is galled and seized on the driveshaft… anyone ever see that before? I know that I didn’t put enough pressure to actually pull the gimbal...

    Affordable fuel injection intriguing

    The self learn is basically fuel trim that goes beyond so it will create a tune eventually. What turned me off from it was Holley basically telling me sorry, a distributor isn’t provided for my engine and that is it. I actually determined that a Delco EST will work with modifications based on...

    5.0 oil weight and amount

    Sadly, possibly not anymore. I have not bought a Wix in a year or so but, word is going around that Napa is no longer sourcing filters from Wix. If the box isn’t marked Wix or Affinia than it’s not a Wix

    Boat

    I think it’s an MFG…. But more importantly it’s dangerous with a rotten transom

    1989 Mercruiser 2.5L 120HP motor overheating trouble shooting

    You either have a blown head gasket, or in need of a valve job or adjustment at least.

    153 head on a 181

    So the ‘86 3.0 head has the same ports as a 2.5?

    1993 OMC 5.8 EFI and drive system conversion to Volvo Penta

    Seloc manuals generally hold up the broken leg of a coffee table. They have accurate specifications but repair procedures are often incorrect. Critical points like shift adjustment is totally wack, for sure on Mercruiser. I’m sure OMC/ Volvo is similar

    153 head on a 181

    Can I put a 153 120hp head on a 181 140hp? I have a 1971 120hp and a 1986 140hp. Want to bolt a Clifford intake up to it but figure the extra displacement would help. Going into my rat rod which is basically a model A frame with a custom built cab

    Affordable fuel injection intriguing

    I’ve given up on the Sniper. I contacted Holley and they basically said they would offer no support for a non approved distributor ( regardless of the fact the software has a setting ) and they basically said the Sniper couldn’t deal with the Mercruiser shift interrupt. With a system that...

    Engine identification

    987124 is an ‘86-‘93 OMC Cobra, and it says 5.0 so that’s either a 302 or a 305. Specific year doesn’t matter much between those years, although the order number is the serial number where you can get the year of manufacture

    4 stroke v 2 stroke. Outboard

    It’s actually just a CDI with a carburetor on that. 40 year old technology. 9.9 and up has EFI in Suzukis lineup

    Affordable fuel injection intriguing

    I think I’m going to go for Sniper. I’ve discovered that the Delco EST is pre phased with the rotor since it’s fully electronic including advance so if I buy the Holley jumper for the pickup and pass it through a drilled hole in the bottom, it’ll just work. The module would exist as a dummy/...

    1990 Rinker 18.6

    Clean the points. If it’s got a pertronix ignitor, it’s probably bad. If it has a Delco EST, it may be wired wrong

    1990 Rinker 18.6

    Check the points. Verify 12v to the + side of the coil. Look at what you have.

    Merc 4.5, any reason I can't just dump the block and manually fill with pg antifreeze?

    Corrosion is the reason that Mercruiser Added it to the manual.

    First boat! 1989 Quantum 1800xb Force 125

    I’m not sure what you mean? That parts boat I chopped wouldn’t have passed a core test almost anywhere. I’ll say my other parts boat a 1988 Regal Medallion that I bought thinking it may be safe for an outing or 2 before blowing it apart for parts never got close to water. Solid floor that...

    Copper head gasket

    Dead soft aluminum would do the same thing as an old school copper gasket, without the galvanic corrosion

    1985 mercruiser 3.0 starter

    If you have an electric motor shop, they can most likely rebuild it. Parts are available if you are familiar. I haven’t rebuilt a starter in a decade, but it’s not terrible.. the starter is a sealed Version ( ignition protected) of an off the shelf starter for an old SBC or whatever.
