I would like to know the approximate cost to change a 9.8 Nissan from a long shaft to a short shaft. I
Thanks! Also I plan to do the work myself and am wonderinng if the parts are readily available.
That conversion is costly. Why do you need to modify LU lenght. In what size boat will the engine be used, is it for fast displacement or planing speeds ?
I am asking for an elderly fishing buddy who has found a longshaft,at a decent price, (950.00) but his jon boat has a 15" transom (of course). He is hoping the change over could be done at a reasonable price. I guess not.
You might be able to use a jack plate. A non adjustable jack plate is pretty inexpensive and relatively easy to install. It's called non adjustable but there's really quite a bit of adjustment by moving the motor to different holes.
A Nissan/Tohatsu 9.8 is a clamp type OB, Other option is to make/buy a 5 inch transom mount. Screw it to transom and sit engine there. If eldery boater likes to cruise at fast displacement speeds not an issue using a long shaft on a short shaft transom. BTW which type, lenght boat and max HP is it rated for ? A jon is a alum boat ?
This is not a exact engine/transom match science doesn't matter if raising transom to 20 in while matching a long shaft engine. The ideal set up height will depend entirely on boat's hul shape, transom height and brand engine model used.
