    Prop size

    Joel, It sounds like we have a similar setup... My 1998 Mack with a Cummins 210 and a 1.22:1 gear has a 17x17, 4 blade. I feel I am a little overpropped however, as I can only achieve 2,500 RPMS WOT. If not overpropped, then I'm likely having a fuel delivery issue... What is the pitch on your...

    26 ft Cummins 6bt

    I initially thought that could be a culprit but Valley Propeller in Ventura says it is galvanic corrosion. Looks comparable to this: https://propspeed.com/media/news/news-item/2020/12/09/corrosion-a-boat-owner%27s-greatest-fear It is a nibral prop… I appreciate the offer of trying yours and...

    26 ft Cummins 6bt

    I have a 4 blade, 17 x 17 Michigan Dyna Quad. I haven’t begun looking at new props yet, but eventually need to. I had some galvanic corrosion on my prop this spring (see photo). Before I went to get a new one I wanted to make sure I resolved the source of corrosion, which I have. My gear is a...

    26 ft Cummins 6bt

    Better late than never…. Wide open in neutral I get just under 2800 RPMs on the tachometer. Now I need to shoot it with a photo tach…

    Fuel Stick 1998 Mackinaw

    Update- i Discovered the easiest way to get some answers. I pulled off the fuel fill shroud and was able to get a measurement of the gunnel side of the tank, and what do you know it was about 6-6.5”. On my boat, I have a 6” round hatch in the floor panel covering my starboard side tank. Through...

    Fuel Stick 1998 Mackinaw

    I just can’t figure out why I’m only getting a reading of 6.5” when full- or when fuel spits out the vents. It’s the same on port and starboard tanks. I’ll have to pull up the floor sooner or later and check my tank…

    Fuel Stick 1998 Mackinaw

    Would anybody here be able to take a picture of their fuel stick next to a tape measure for me? Mine did not come with one, and I would love to have one with the correct markings. I assume the gasoline and diesel tanks are the same, I have a Cummins diesel. Everyone says I should be able to get...

    26 ft Cummins 6bt

    I want to say around 750… I know it idles less than 800. I’d love to know what that tells you. I’ll confirm this weekend. And I checked it with a shitty RPM gauge and it still seemed just under 2,600, but not sure how much I trusted that gauge. I generally cruise around 2,000 so if I am...

    26 ft Cummins 6bt

    For what it’s worth, I’ve got the same engine and an old Michigan 17 x 17. I’m maxing out at 2,550 rpm’s, and plan to get a new prop in the not too far future. I have some minor pitting on the prop and have bottom paint. I’m guessing without that, I’d be able to achieve 2,600 or more, what the...

    What kind of condition is the tub in, and would you be interested in selling it? I assume it no longer fits… My 1998 mackinaw did not come with one…

    Hull Zinc On Transom_ 260 Mackinaw

    Yes, good article, easier to understand. I’ll keep this one for reference.

    Hull Zinc On Transom_ 260 Mackinaw

    Still learning about the bonding system in place on my 260 Mack. It appears that all thru hulls, and my rudder, end up bonding (via green wire) to the aluminum cross brace which supports the deck, just aft of the engine. Is this a “common bond” point of some kind? Anyone have an...
