Hey Sam, You beat me to it. You need wing plates welded on and tie bar is not cheap. Power steering pump wing plates and tie bar could be in the area of 5 to 10 grand alone just for product. No need for remote oil tanks tho anymore.

Not to mention a new wire harnesses depending on what you have also for the DTS. And if you want a nice heavy duty steering pump from Latham instead of the lightweight weak mercury one add another $2500.00 dollars to the mix. I would figure add another $15k to the price of the motors. Trust me I have already done the spreadsheet.
Did I mention extended warranties for another 9k?????

As noted, it's not a simple engine swap. More than the engine cost for sure, and wiring for drive by wire/DTS controls, can add up.

Gary P I like your discription under "My boats" Skater 30 (It's my brothers!).

We are all brothers here so welcome aboard.

Skate - Yes, it's really true. I am very blessed to have a brother that includes me in his boating! We run some poker runs together (Lake Erie/Buffalo, Seneca Lake, etc, and have a blast together. We grew up with boats, but nothing like what's out there today. Back in the '60's, our runabout was considered "fast" at 33-35 MPH! LOL
