    40 hp Lark electric shift lower unit

    I have a 1964 40 hp Lark Electric shift that is stiff (hard to turn the flywheel and turns the prop in forward). I can tell that it is stiff in the lower unit rather than the powerhead. I'll be removing and opening it to see what the problem is. <br /><br />My question is, is this LU the same...

    What fuel-oil mix? 1961 75 hp V4

    Dad just got a 19' Larson boat with a 1961 V4 75 hp Johnson (model V4A-13). What is the proper oil mixture for this, 24:1, 32:1, 50:1? If I don't see an answer to this before we take it out, I'll suggest he tries 32:1 as a middle ground when we fill these empty and near empty tanks. (Never go...

    tachometers for vintage outboards?

    I'm looking for a tachometer for one or more of my older 30-40 hp J/E outboards (2-3 cylinders). Does anyone know of any compatible tachs on the market? Teleflex only works on motors with alternator and points (not generator and mag), and the tinytech ones I read about in another post don't...

    New tachs on old motors

    We have older ('60s) Johnson/Evinrude 40-75 hp motors and the (Teleflex) tachs I see in Cabela's marine catalog say "direct plug-in" wire harness for J/E engines. Are they talking about recent engines only? Do they generally include hookup directions for the older models as well? I haven't...

    Loran antennas

    I got a couple Loran receivers a couple years ago, cheap. To test them out or use them on a boat, what is the length of a Loran antenna? Or so I can calculate it myself (Ham Radio operator), What is the frequency of the Loran signals?<br /><br />BTW, I live within 40 miles of a Loran station...

    formula to find prop pitch from hp and boat size?

    I've seen information on figuring the speed of your boat based on engine RPM, LU gearing and prop pitch. But is there a formula to determine the optimum pitch based on boat size, and motor hp? <br />A 14' and 15' here, both with 40 hp 'rudes have 10x15 props and a 19' with 75 hp johnny has a...

    3.5 hp Sears needs reeds, what year?

    I have a (IIRC) 3.5 hp Sears outboard that needs reed valves. One of the four reeds in the assembly is bent. The air cooled powerhead is a Tecumseh (on the flywheel), so maybe I can get reeds from my local small engine shop (Tec. and Briggs authorized shop). Years ago just before I discovered...

    Licensing trailer in MN

    A few years ago Dad bought a Yacht Club trailer to haul my brother's "new" 14' freebie boat on. The licence plate from Dad's other trailer was used to move it on the roads. Since then, he has lost track of the bill of sale and/or title and has forgotten who he bought it from. <br /><br />Now...

    add-on keel or skeg?

    Dad just got an old lapstrake style fiberglass 19' Larson with a short shaft v4 Johnson 75 hp (yes, short, it's a 15" transom). I noticed during the test run before purchase that it really leans before biting into a turn and easily ventilates the prop. Would there be any decent way of adding a...

    Filling gelcoat cracks

    My '64 Glastron Skiflite 142 has a few cracks in the deck gelcoat which I believe are mostly from age shrinkage. What is the best filler to use in these thin cracks? I need something thin enough to flow or push in (putty knife?). I'm thinking about then repainting the boat once the cracks are...

    Stuck flywheel

    I have a '64 Evinrude Lark 40 hp. I've been trying to pull the flywheel to check the points and condenser, but it won't budge. I have applied penetrating oil to the shaft just under the nut a couple times. I have a wheel puller sitting with pressure on the shaft a few days and have been...

    need hydraulic cylinder for power tilt

    I have a Leg-O-Lift system on my '64 Glasstron Skiflite 142, everything but the hydraulic cylinders. Can anyone suggest where I can find these or something suitable to lift my 40hp Evinrude? Somewhere around 13" compressed.

    Repainting 1957 Evinrude, what color?

    What is the original color(s) of the 1957 30 hp Evinrude Lark outboard? The one I have appears to have been spray painted black with some blue showing through.<br /><br />What happened to my original post? I can find it listed in a search, but the link takes me to a different post!

    12v system and 24v trolling?

    My brother is considering getting a 24v troller for his 19' cuddy with Mercruiser 1 I/O (boat converted in the past by someone else from OB). This is a project boat, so he has plenty of time to consider his options. Are there any existing systems out there to charge two 12v batteries in...
