    19' to 21' Bowriders or Sport Decks

    On your question of bow riders, deep V assumed monohull, vs deck boat type more of a modified hull, and big water, deep V hands down and totally agree with today's outboard power. $40-50k budget "new" won't get you very far in today's market at 18-21' big water boat and adequate power and...

    Transducer interference

    The guys that were in on the initial development of the Hummingbird used to work in my area of an OEM provider of electronic equipment. I think that original development was in Alabama and one of the popular lure mfgrs/designers was part of the startup funding.....it's been a long time and...

    Smarttabs

    Having experienced chine walking on a particular boat, starting at a particular speed/trim angle, would you mind taking the time to explain your initial situation and then your adding STs and the initial results, and the final results once you educated yourself and found the final sweet spot...

    Water coming in transom

    I'd say that the bearing carrier, assuming the prop shaft bearing carrier supporting the rear prop shaft bearing has nothing to do with water of the sort. Usually it's the deflector plate mounted on the front (leading edge) of the LU about 2" above the AV plate being under water that causes...

    For those fishing enthusiasts - what's your style of boat?

    BIL ran a charter 20' aluminum air boat, Cadillac V8, out of Sugarloaf Key for a number of years there in the out back, West side. Went down to visit one winter. Got on the plane in Dallas in overcoats and all.....got off in shorts. Caught some Grouper on the trip. Some of the tastiest fish...

    97, 75hp,3 cylinder Merc - Questions about the shift slide and remote control

    I haven't seen one. Could depend on the cable mfgr. as to how long is the brass, threaded barrel, what kind of control you are using, this and that variable. The barrel and plastic slot location is indicated right there in your photo with the shifter and throttle barrels fitting into the...

    Prop selection help

    Flow torque has a square receiver cast into the hub. Rubber hub I assume is round as the rubber hub is designed to slip upon striking an object of sufficient size and upon the operator reducing the RPMs to idle, shifting into N, then back to F and accelerating, it will reseat and you be on your...

    1992 75hp Mercury 2-stroke, overheating warning

    The OEM stat in my 2002 90 was stamped 143F opening temp. The 2002 115 I acquired last year had a 125F stat and I know not of the origin. The service manual for all these series of engines, including your year-model states that the alarm temp sounds at 195 (with tolerances of probably 5-10%)...

    Buying Used Boat

    My experience has been rubber problems, fuel lines and wiring harnesses on older boats that used rubber rather than thermoplastic for insulation. Other problem would be salt water operation without engine being flushed after usage and corrosion/marine fungus/slime on lower units caused my...

    Adding extra riding seats to small fiberglass bass boat

    I'd suggest a light weight, lightly padded to keep the weight down, captain's chair with arm rests on a short adjustable pedestal. Mount to the deck (floor) with the 9-12" regular pedestal mounting flange with the 2" pedestal mounting hole. West Marine has something that will work: Model...

    Mercury 9.9 propshaft removal from bearing carrier

    On the time to buy new one concept, I have the same opinion. You have a "device" that is x years old with y operating hours. A repair of one element costs ⅓ the cost of the new unit and considering inconvenience in the tear down process and time involved, waiting on parts once identified and...

    Mercury 150-water from lower unit when ear muff flushing normal?

    Water goes in water goes out. The midsection is cooled with water plus the exhaust cover and engine block are cooled. All but the pee stream and an RPM dependent amount of water comes/is blown out of the "exhaust relief" ports just below the main engine block cowling at the top rear of the mid...

    Go to the top of this page and work your way into Props. Fill in the questions...you exact engine model, and look at the props. Usually the correct hub number is either part of the price or available at extra cost. Maybe your prop and correct hub number is posted. Some hubs fit tighter...

    Aluminum small hull design

    Here are some pictures of a Duracraft which, in the time, was very similar to Alumacraft construction. You get the high tensile aluminum and it resists bending up to it's stress limit (work hardened joint, if hard enough fractures on the 2nd or 3rd iteration)....where it starts to molecular...

    Looking for Opinions on Super Bowriders

    Totally agree having BTDT with an 18' Caravelle tri-hull back in the early '70's. Mono hulls have solved a lot of the problems of rough ride (deep V design) and water over the bow (higher gunwale off the water) and the length you are mentioning helps solve the problem unless you get into some...

    Mercury 9.9 propshaft removal from bearing carrier

    " I find it hard to believe that the prop turned a stainless steel shaft like that when it has a rubber bushing inside to prevent damage when hitting stuff." Me too. When I saw the shaft I couldn't believe my eyes.....on a 10 hp engine no less....a 200 anything's possible, but on 10?????. I'd...
