    Speedo Pitot Tube Replacement

    Speedo doesn't work, checked out pitot tube, it's cracked on the end. Ordered another, replaced defective one. Q: Is the rubber hose length critical? The new pitot tube connection must be a bit higher on the transom, cause what was a straight run, now has to be rerouted to take up extra slack. I...

    Oli Filter for 1985 MerCruiser 3.0

    Did a bit of research on this, but only found conflicting information. Also, scanned the engine manual and found no oil filter number in there anywhere. It's a 1985 MerCruiser 3.0L 140. Reading the posts from various places, most warn against using Fram filters. I have a NAPA store up the...

    I Smell Fuel...

    When I take the cover off, I get a strong wiff of fumes... now I've been working on this boat all summer, so maybe that's expected, still it's a little concerning. There's a bit of fluid in the bilge, probably some oil in there. And the cover is old, maybe permeated with fuel smells. It's a...

    Reliable Sure Lube Trailer Hubs Q

    How much grease should these hubs take? Watched a youtube video and the guy had an automatic pump and he ran that for quite a while before the old grease started to come out. I just hand pumped a tube of marine grease in each hub, but no old grease came out. No idea of the maintenance schedule...

    Grease Gun - Stuck on Nipple

    This is weird... borrowed a grease gun, went to use it and there's a nipple stuck in the end. No matter what I did, could not remove that sucker. So, I went to the hardware store, picked up another connector fitting. Attached the grease gun to one of my outdrive nipples, greased it up, but can't...

    Garmin GPS Recommendations?

    I have a small (17') trailered boat that I use in different waterways (bays, rivers, etc) and I'm looking for a GPS unit that I can install on the dash. I'm familiar with Garmin so I'd like to stick with that brand. Screen size can be on the small side (4" or so) with a color map display and...

    Carb Throttle Linkage Q

    More often than not, when the throttle is returned to neutral, the carb doesn't follow. Yet, if I put pressure on the idle link, the rpms drop down to where it should be. What causes sticky linkage, no return to idle? I tried spray lube, no effect. I'm wondering if it's alignment? Also, this...

    MerCruiser Won't Turn Over

    While working on an acceleration problem, the starter suddenly won't turn over the engine, just clicks. Checked the battery, it was good, threw a charge on it anyway. Also, the trim motor inop, up or down, does the same thing, just clicks. Not sure where to look? Any ideas?

    Mercruiser 3.0L Alpha 1 up motor doesn't always engage

    This just started - when pressing the "trailer" button or "up" toggle for raising the outdrive, no action. I can hear the solenoid click, but the motor doesn't activate. The "down" works. But if I press the button dozens of times, once in a while, it will activate and as long as I hold the...
