    Steering Controls or Stick Controls for Inflatable?

    A center console usually has rear seat and front seat which takes lots of needed space in a short Sib like yours. You can tiller drive very comfy with just a spare cushioned seat installed close to tiller at hand reach, besides will have lots of space to store whatever you like carrying when...

    Prop Cavitating (catching air?)

    Recapitulating Did not payed much attention at the date that OB was manufactured, but that's a 17 year oldie. Don't know if bought new, second hand, with low, many hours use, anyway prop hubs don't last that long if OB was used, abused a lot. Combo has too many issues to deal with. If wanting...

    Pulled Threads.-

    Timesert kits are nice and costly, but for the non experienced seems bit complicated to install, too much tooling, have worked with Heli Coils before. This is the OEM cylinder head bolt with measurements. Was wondering if this repair kit would be appropriate to fit most of the 22 mm threaded...

    Nissan 15 hp lower unit removal

    Sorry number 25 corresponds to post 8. Newer lower leg units are like this one, does not show part 26 whatsoever. It's as simple as removing upper coupler pin and 4 lower bolts and that's it.. Assume that never before have stripped a lower leg, it that's so, your whole issue is a seizure...

    Head Gasket Issue.-

    As a preventive maintenance will like to change my current head gasket, this one it's not a OEM gasket, it's hand made locally to factory specs but does not have the sealing compound spread out on both sides that seals the gasket to both mating surfaces with initial heat when OB is started. Is...

    Tohatsu 30hp top speed

    Personally don't like centre consoles, takes too much needed deck space which is a must have. If being a 2 piece hull/deck Rib, an excellent idea is to install just a seat & locker aft transom, that way will tiller drive more comfy seated. Driving seated on tubes while throttling with...

    Myths & Mismatches.-

    Was not going to respond to newer post about these boat/transom mismatches as you like watching your side of the coin, that's large boats with large HP-OB's with electric trim. The issue with big shot boaters is that they ignore or don't care the least at which lower leg height water flow passes...

    Trailer Question for My 14 foot inflatable

    1-Won't fit, Sib is too large. 2-Need a trailer with side bunks, Sib's width for lower tubes to rest nicely on bunks. 3-OB must rest with lower transom supported on top of a wooden, metal bar installed parallel to lower transom as in pic. Ideal for long distance hauling and minimum transom...

    OB trim

    Welcome to Iboats, Firstly need to inflate tubes and keel to their factory working parameters, min air pressure should be 3.0 PSI to achieve a firm inflatable boat. A 4 HP-OB is a very underpowered OB powering a realtive short size inflatable. probably just good for fast displacement speed...

    Myths & Mismatches.-

    Read repetitive posts of newbie boaters requesting info about which should be the correct OB height when combo undergoes its first dry installation process. The Automatic Rule of Thumb Answer is : “Even With Hull” (EWH) To start with this rule ain’t such, all OB’s brands Owner’s Manuals state...
