    Who has installed Helicoils ?

    It will work better because it's SS not cast alminum and its slicker so it's easier to get the correct torque....like wet and dry thread torques on bolts.

    Prop hight

    In 1972 I bought a new Johnson 125 on an 18 ft. FG Caravelle open bow, tri-hull with a good amount of dead rise all the way to the transom with relatively heavy construction for a really nice comfortable ride. The engine sat on the transom (PTT wasn't available for engines till the following...

    Who has installed Helicoils ?

    I'd do the work Matt recommended and then install whatever length you have and when finished take a 4 or 4 1/2" cut-off wheel and trim to fit. The usual practice is to knock the tang off the bottom after insertion but since you are bottoming out seems like a moot point. Another option is to...

    Fore & Aft Play In Prop Shaft ?

    Well maybe you don't have an overrun clutch.....according to Faszbullet some engines don't have one.....I can't imagine that but what do I know...... I am not familiar with your boat. Go to a dealer of your boat and do the test I mentioned on new boats then worry about it if different!

    3 Blade or 4 blade prop?

    I bought my first boat as a junior in high school in 1958. I've been boating ever since. I learn something different on every outing I have enjoyed (or otherwise) over the years. You never know it all......

    Pontoon prop

    Guessing the Big Foot gear ratio at 2.33 if your BF is using the standard LU that comes on the 90 hp engine.....if not correct it in the equation and move on. You didn't say how far above 6k it runs at WOT....guess on this 6500 for a number. Assume your prop slip to be 20 %...have no idea as...

    Which deckboat 17-19 foot

    Build yourself a shell covering out in the yard. A tri hull pontoon, referred to as a "Tri-toon" can be had with a 300 HP engine and do 65 MPH if that's your cup of tea.....and there is a place for the "head" (potty in nautical terms).

    First post, new (to me) boat, and how badly did I screw up?

    Check around for fiberglass repair shops. May not be a boat repair facility...may be a custom car outfit that does FG work. They have the tools, parts, and expertise........ For what you paid for what looks like a very fixable boat, you should be able to spend a few bucks to get her ready for...

    Which deckboat 17-19 foot

    My main concern when selecting a boat is smooth ride in a chop because around here the wind always blows. Back in the 70's "Deck Boat" I think was the brand that had a flat hull with a suggestion of a V at the bow. The ride was brutal!!!!! Later somewhat Veed hulls became available. Other...

    Cut Holes for Improving Engine Access

    My I/Os had a removable engine cover...top, sides and front, that just slipped in place, weighed about 50#, easily removed, or just tilted forward out of the way. Hinged front would work for the above if you wanted to secure it. If seats are in the way (driver and shotgun) with a couple of...

    The newest outboard from Mercury

    Yamaha or Suzuki Motors.-

    Suzuki and Yamaha have both been in the 2 stroke business for decades. Rumor has it that Yamaha followed the OMC design when entering the market...forget the year. Don't know the Suzuki background. Yamaha seems to be a wider market but I have heard some "gee I want to buy one" desirable...

    2004 Mecury 90 hp wont start

    In Roscoe's solution, the "kill switch" is an ignition killing switch at the operator's station that is made for a lanyard attached to your person while operating the boat....if you have the lanyard attached and fall overboard, the boat stops. If his starting procedure doesn't work: You said...

    Steering

    Question was answered but a little extra: Back in the 50's when Lone Star Aluminum boats were in my boating circles, cable steering was the norm with the drums under the dash and if a runabout, a cable usually went down each side of the boat attached at the front and rear with pulleys, a pulley...

    3 Blade or 4 blade prop?

    I was running a 3 blade 20P early edition Laser II which would run 48 on calm water, summer heat. As you are talking here, I like to run around 3000 RPM and 25 mph most of the time so I bought a Solace 4 blade 19P. I lost 3 mph of top end (and some RPM) which I don't miss (because I know I can...

    08' Merc 90hp --Ditching The Oil pump/going mixed fuel..

    I removed the automatic oiler in my 2002 90 hp. It was really complicated......I undid 3 screws holding the pump in place and temporarily disconnected one oil line attached to it to get the pump out where I could grasp the geared drive shaft and pull it out.....which I did. I put the hose back...

    Boat going in reverse instead of forward

    Thanks for the intro but I can only try to help. Force (Mercury Marine product) was initially a West Bend, then Chrysler, then early model Force...Mercury's low ball market entry, and later incorporating some of Mercury's parts/designs. I don't think it was ever intended to enter the up scale...

    1985 Mercury 85hp (4 cyl) runs great for 20 minutes then boggs down

    Test them. Get a container of fuel and set the float in it with you propping up the pivotal end like happens in the carb. If plastic, it ought to float like a cork on your fishing rod...right on top of the fuel since objects displace their weight in a liquid and a plastic float is near...

    Used Outboard Sites and Replacement Advice

    The John/Jon is defined as a flat bottom boat.....popular in rivers and protected waters. Aluminum Johns are about all that are available in my boating circles so you have a light weight boat with an excellent planing hull...nice and flat, especially at the transom, on a light weight boat. I...
