    How well will my 40hp mariner move this boat you figure?

    I have a 15 and a half aluminum with my 40 on it and it moves really quite well...seems almost too big for the boat weight wise....getting to the point here i am looking at a fully welded aluminum boat. The boat itself is made entirely from 3/16th aluminum nickel stuff (i'm no metalurgist but...

    1986 25 Hp Merc dies @ half throttle

    My 86 merc ser. #6008686 sputters out at half throttle on both acceleration and deceleration. I took it to the mechanic and he said they couldnt finger the problem and suggested I throw parts at it until it's fixed. He said to change the cdi which costs more then what i paid for the motor. I...

    86' 25hp Merc Tiller Dies at half throttle

    My 86 two stroke merc dies at half throttle. I have new fuel lines, new filters, new gas, cleaned carbs, new plugs, and new coils. When none of this helped the problem of the motor dying at half throttle I took it to the marine mechanic who after an analysis said he didnt know what was wrong...

    tiller mounting problems...need input

    i've built up this 16' aluminum boat and turned it into a tiller. Long story short i have it done and have rebuilt the transom. My first motor (25 hp merc) has a shot cdi so i ended up buying a 40 hp mariner. The mariner seems to have a longer shaft (the boat is a longshaft transom) then the...

    Mariner maintenance?

    i just bought a new-to-me mariner 40hp longshaft tiller and it's really a gem. It's either freshly rebuilt or has been rarely used. Anyhow, i want to keep this thing in top notch running condition. Any tips or suggestions for maintenance or things to look out for? I do believe it's a 94.

    Boat "bobs" while cruising - why?

    I have a 16' mirrocraft (it's old) that was a cruiser but i cut the top of the front off and turned it into a tiller. It's a great boat - awesome actually - however now with my 40 hp mariner longshaft on it it tends to bob when i get up to speed. My transom is rated for 75 hp according to the...

    86' 25hp Merc Tiller in the shop

    I finally gave up and took it in to the shop. That motor starts easily on the first pull and purrs like a kitten....up until half throttle...then she'd die out...oh she'd fire right up again when you give her a pull and move around fine until you got around that half throttle mark. So I pull it...

    Still sputtering slightly at half throttle going up or down

    I changed plugs, coils, sparkplug wires, new filter element, new gas with some sta-bil added. I can get to wide open throttle now but it's slow to respond and still kinda sputtery around half throttle when i'm both powering up and powering down.....i'd like to clean the carb but i'm not sure...

    obsolete parts

    I recently acquired a 28 horse johnson-rude (i have yet to take delivery of the motor) sans tiller. Where is the cheapest place to get a tiller handle for this ol' girl. I am guestimating it's a 70's era. When i do pick up the motor i will have the specific motor we need.

    Foam for under floor

    I am going to lay down a new floor shortly in my aluminum boat. At the edges of the boat, where the sides meet the floor there are no tabs to support the edges of the plywood. To support the extreme edges of my floor i was thinking of just pouring some foam down and then fasten the floor on...

    How do you raise a transom?

    I have a 14' aluminum with a 9.9 hp shortshaft tiller on it and I also have a 25 hp merc tiller longshaft. I was told by a lund dealer that they "build up" transoms for long shaft motors all the time. If they can do it than so can I...except i'm not sure how. Way I figure it, do i pry the...

    70's 25hp Merc bogs down under load

    I bought an old 25 hp merc longshaft tiller outboard last year. Took it to my boat mechanic who ordered a bunch of long defunct parts and got her running again. I then proceeded to use the motor about a week or so later (on a boat that was meant for a short shaft tiller) and the merc would start...

    Rebuilding a '63 Mirrocraft into a tiller

    It's a Mirrocraft model # 1263, 16 footer with a 20" inch transom. It has three supports that brace the stern against the motor...does this mean it has a high horsepower rating? As you can see in the pics it used to have a steering wheel and i want to rebuild into a tiller. I have a 25...

    Question for those smarter than I

I wish to rebuild the boat completely as it's already stripped and turn it into a tiller. My question pertains to strength...
