Re: outboard to inboard conversion
An inboard? Or an inboard/outboard? Either way you are looking at possibly thousands of dollars and a tremendous amount of work.
A true inboard would require a transmission, propshaft and ALLOT of hull restructure work.
An I/O would also require allot of structure work ....... transom stringers and more
Conversions on a 1989 boat are not worth the money or effort. Ypou could purchase another boat for what you would have invested. Look at NADA and you will see that a 1989 Cuddy even larger then yours sells for under $4500 and a conversion will cost at least that and more.
