and just cos its got a bigger engine doesnt mean shit, personally, I don't see the point of having an engine any bigger than 40hp on a boat of that size and type - any bigger will not actually increase its top speed.
Also the fin things above the prop have to be inline with the lowest part of the hull. If the fin things are below this point the boats ability is affected (stability,turning etc etc)
I would say it's worth 2-3 grand.
Sorry to hijack thread but I too am selling a boat.
17ft/5mtrs
70hp evinrude with $2000 worth of rebuild receipts.
new floor timber beams and all.
Fresh coat of paint (rta orange) and white base.
New windscreen with canopy.
strengthened transom with 4mm chequre plate.
Will or will not be registered depending on available money.
Trailer will eventually need repairing but Have started on that already.
What's it worth?
