    10ft inflatable rated for 15 hp max (Thinking about adding a 20hp engine?!!)

    Why would someone prefer a manual winch versus an electric one. Just press a button and near instant voila. Winching up manually a boat at a steep ramp is not same as winching it down. It's like hikking up a hill which is near easy as opposed descending same in which your legs strive and...

    When sea cond gets windy & wavy hard hull slams badly into the water bed. Doesn't happen at plane speed as one would imagine, usually at slow plane, that's what comes inmediately after passing fast displacement speed. I'm begining to feel the slam pain effects on my lower spine but not to the...

    I'm not a big fan adding extra chain between anchor and anchor line due to the noise it produces up front while nested at bow when encountering choppy seas cond, but for 10 bucks could't say no to this nice 1/2 meter thick heavy stainless steel chain. Has a quick release front shackle that...

    anti ventilation plate question

    JimS, Glad to know that I'm not alone on this misunderstood best engine/transom height crusade. This was a testlike for Boater 123, as the cast on stone reference says that having AV plate even with or slight under keel produces the "best" performance. Was wondering which type of...

    Guess what... My state of the art Tiny Tach installation stop working after just 1/2 hour use. Assumed it was due to having wrapped pick up wire on the outter sleeve that protects plug wire instead doing so over the wire itself or cutting to a shorter length to suit internal less cable routing...

    Before my new 8.5 pitch prop arrives. have decided to dispense off my throttle limiter to allow WOT operation by monitoring RPM with a Tiny Tach state of the art installation next to throttle grip.
