    HYDROFOIL

    If the performance gains , fuel burn ,trim angles , are that much better or are suited for most of the small boat ,cruisers etc . Why isn't Mercruiser, Volvo , any Out Board mfg integrating them into there housing as one piece? And it would be slimmer than a bolt on , meaning even better...

    2002 Sea Hunt 172 vs Key West 1720.

    Going of shore in a 17' boat is a crap shoot . How far is offshore ? 10 miles ,20 miles or more ? Unless the water is glass and you've been sitting under a high pressure system for days , I wouldn't venture more than a few miles from shore in a 17' ,unless it was a Whaler ,for obvious reasons .

    Opinions on 2005 Hydra Sport 23’ WA

    I believe the " exhaust " issues are for salt water engine's. Engine life used to be a lot shorter , things have changed over the years . More frequent oil changes, tolerances being more precise, materials used , research and development, addressing what and why , broke on previous models ...

    Opinions on 2005 Hydra Sport 23’ WA

    I would be hiring a surveyor , they will give you a fair value and more importantly , check for moisture in the hull and decks . They usually don't go through the motor , but check everything else out . Depending on where you live , 4- 600 $ to have it done . If your going to insure it , make...

    Fuel capacity for 1990 sea nymph

    Should be a tag or plate on the top of the fuel tank by the sending unit with the capacity marked down . If not you need width , length and height of tank ,then math 101 . Keep in mind 10-15% of the tank is not usable , depending on height and location of pick up tube .

    Lake Decatur - good for boating & fishing?

    Under those circumstances I would be looking at a jet drive boat , Yamaha comes to mind . Or a outboard converted to jet drive . As far as fishing goes , probably a Facebook page on Lake Whatever Fishing group.

    Transom plate sealant question

    Usually when metal plates are added the transom itself is rotted out . This would be the first thing I would verify ,one way or another . As far as sealant goes , 3m4200 is what I would use . It's the same as the 5200 except not permanent.

    Suggestions on how to fill my onboard gas tank?

    A shaker siphon hose will reach as far as you want. You can put the shaker device on any length hose as long as the portable tanks are higher than your boat ,gravity works . Start the siphon and you can stop it at any time at the tank it's going into , with zero spillage .

    Trim sender

    I wouldn't even bother trying to fix it . If I'm in a boat with a working gauge , I never look at it . You should be able to feel what the hull is doing in relation to the trim of the drive . In most cases ,once on a plane , you trim up until you hear the rpms pick up to the point where it's...

    Hull damage while lifting? Donzi

    Most hulls over 24 ' do not have " cross ribs " , usually a bulkhead serves that purpose. With a cabin type boat that is usually located right in front of the helm , or where the stairs are . It's pretty much the only location to tie the two sides together , besides the stern and bow . You...

    Hull damage while lifting? Donzi

    The lifting points would be where the Z or I is in Donzi and between the aft and midship portholes , closer to the midship , as near as I can tell . Twin I/Os is going to have most of your weight in the stern . The stern strap should be pretty much under the engines. I don't think the Marina...

    Flood damaged Boat Lifts

    3 D printer might be the answer . I'm sure there are people in your area that do that type of thing.

    Need help finding controls for Mercury Sterndrive.

    Have you verified current going to the switches and if so , current going to the pump ? I would be looking at the solenoid before the actual switches . They usually let go 1st . A volt meter or test light is something that should be in your tool bag when diagnosing electrical issues . Or you can...

    Old Cobia?

    The " Cobia " decal could be the model ,not the MFG . Have you confirmed there are or are not any hull ID number's engraved on the transom ?

    Old Cobia?

    Ok ,I'll bite , have you checked the upper right hand corner on the outside of the stern for ID engraved numbers ,letters ? That will tell us if it's pre 73 . As far as the gunwale goes , no idea why the gutter is there , can't think of anything it would be useful for if fishing . Clamming or...

    Pricing restored boats

    You should research 1st before restoring a boat . There are very few aluminum boats that are desirable to a collector. Feather Craft comes to mind and you have to have the right model. Usually finned fiberglass hulls bring the most money. I'm thinking your set up is worth 1,000 - 1500. A 14 '...

    Crestliner Serial Number ID

    Might try getting in touch with Crestliner and see if they have any info , records of the build . Boston Whalers " serial " number are interpreted for you by them , model etc . So there is a possibility Crestliner can do the same .

    4.3 spark arrestor replacements

    So you don't want to spend a " boatload of money " . Does a 4 barrel carb ,400.00 and a new SSteel prop , 4-500.00 along with head gaskets , possibly premium gas equal a boatload of money for a 1988 set up ? You will need a new prop if you're bumping up your HP .
