    Lund max engine weight

    I’ve got a 2001 Lund Pro Sport 1600 with a 70hp 2 stroke Johnson. I’m thinking of upgrading to a 90hp 4 stroke, but I’m concerned about the weight. The Lund is rated for a 90, which for 2001 weighed 319 lbs. A new Yamaha 90 4 stroke weighs 353 lb. Will that extra 34 lbs stress out the transom on...

    Johnson throttle control problem

    I have an older (1980's vintage) Johnson 25hp on my pontoon boat, with Johnson controls attached. Recently, the throttle control stopped working. It appears as though the large cam which pushes open the throttle mechanism has become detached from whatever cable is supposed to operate it. What...

    E-Tec vs Yamaha 4 stroke for pontoon performance

    I am considering an upgrade of the 25hp Johnson on our Leisure Island 16 ft pontoon boat, to either an E-Tec 40 or a Yamaha 4 stroke. I was surprised to find that the Yamaha is a much lighter motor. What else should I consider, aside from getting a newer pontoon boat altogether?

    Specs for 2001 Johnson 90 2 stroke

    I've looked at Nadaguides and cannot find the specs for my 2001 90 hp Johnson 2 stroke. I am trying to find what the weight of it is, so I can find a similarly weighted 4 stroke to replace it with. Any useful links?

    Leisure Island Splash Plate Replacement

    I have a 16' Leisure Island and I took it over to a welder to get its rusted-through splash plate replaced. It appears to be a sheet metal piece bolted to the transom frame. The welder advised that the transom frame appeared to be galvanized and therefore unsuitable for welding, and that the...

    Short Pontoon, Clearance Problem on Trailer

    I have a 16' Leisure Island pontoon boat with a 25hp Johnson on it. The smallest scissor-lift trailer I could get at T & M Marine in Grand Rapids is one made for 19-21 ft pontoons. The problem is that the motor mount that hangs off the frame fouls one of the three supports on the scissor lift...

    Lund Newbie Here

    A summer neighbor of mine is selling what appears to be a 2001 Lund Pro Sport 1600, with walk through windshield and canvas top, 4 seats, and a 70 HP Johnson motor. The first thing that confused me is that the seller referred to the boat as an "Alaskan", which clearly does not seem to be the...

    Trailer for a 1985 16 foot Leisure Island Pontoon Boat

    Well, I have determined that Rover (my 1985 16' Leisure Island pontoon boat) needs a trailer. Does anyone know the specs I need to provide the trailer vendor so that I get the right size. The scissor lifts appear to be easier to load and more flexible with respect to the size of the boat, but...

    Steering wheel swap

    The steering wheel on my pontoon is tiny. I have seen more appropriately sized steering wheels on other pontoons, is this an easy swap? Thanks in advance for the help. UB

    Motor Mount Rusted Through

    I picked up a beater Leisure Island 16' er last year and launched her this spring. She has a 25 Johnson that runs well. My question is about the motor mount forward of the transom, the flat piece of sheet metal you look down upon from the back gate. Mine is pretty well rusted through. I am...

    1965 3HP Lightwin Fuel - Oil Mix

    Just picked up a 3HP Lightwin (1965) in the Twin Cities. From what I can tell, the manual specifies 50:1. Conventional wisdom on the non-repair board appears to converge on 24:1, since the 3HP ran the plain bushings longer than the larger motors. I am reading here on this board that many run...

    New LighTwin Owner

    Just scored this http://minneapolis.craigslist.org/hnp/boa/2985752590.html, looking for the basic information: year of manufacture, fuel / oil ratio, and things to look out for. Fortunately, the little town closest by our lake has an excellent marine mechanic who specializes in "vintage"...

    Sea King

    Newb question: Did Sea King motors ever stop being OMC motors? Not seeing a separate Sea King forum, I suppose this group might know the answer. I am considering the following http://minneapolis.craigslist.org/ank/boa/2970977111.html for my Grumman 17' squareback canoe. Thanks in advance for...

    Mounting Depth / Fish Finder

    Being new to pontoons, I thought I would query the collective wisdom and ask: Where and how do you all mount the transponders for your depth / fish finders? I am also open to suggestions for brands or models that work particularly well on pontoons. I thank you all in advance for the help...

    Best Motor for a Grumman Canoe

    I am about to inherit a Grumman 17.5 foot canoe with a square back. I am guessing that it dates to 1975 or so. Does anyone here have any experience putting a small motor on one of these things? Would a 3.5-5.5 HP motor push it along OK? I think it would be a nice "launch" to use to get back and...

    MN Newbie

    Wife and I recently purchased an island with a 1/2 built cabin on it in Northern Minnesota. Naturally, we were advised to purchase a pontoon! We paid $1800 for a 1985 16 foot pontoon with a 25 HP Johnson on it. Seemed a fair price, given the comparables on CL in Duluth and the Twin Cities. The...
