Boat Lift Conversion

[weinbergm13]

First, thank you for the add!
I have the option to acquire a relatively new 4 post roll able boat lift rated for 4,000 lbs from my in-laws
Good condition and have used it with their boat several times.
Their boat is a I/O and I have a 1997 Sport Nautique which of course is an inboard.
Question, can the boatlift be retro-fitted or adjusted for my boat lift?
Do they sell accessories for this type of thing?
Any insight or advice would be greatly apprecaited!

Thank you

You should be ok on weight as I think your boat (sport nautique, not Super sport) is around 3K. Many lifts can be reconfigured for various boats. I would try to find out the lift manufacturer and contact them directly with your question. One think you need to look at is clearance for the tracking fins and to be sure that your shaft and prop do not hit.

Thank you! Yes that is correct, 2,700 dry weight.
Good call, working on that now.
Is there a good way or place to look for deciding the height of the bunks and the distance between them?
This should then give me the proper clearance for the fins and prop.
That is my biggest worry is not having enough clearance for them!

Thank you again

I just bought a used Shorestation for my 05 SANTE. I had to do some modifications. Main thing i did was buy 2 12' 2"x8" and some heavy duty angle brackets to make bunks out of. I probably should have gone with 2"x10" boards, but I can swap them out next year.

I measured the outermost protrusions from the bottom of the boat. In my case it was the paddle wheel and the ballast intakes, and gave myself a few inches of wiggle room. I think I ended up with the bunks 32" apart.

Re setting lift clearances and bunk widths...you can use your trailer as a guide for both measurements.

Excellent, thank you! Sounds pretty straightforward.

I emailed info@nautique.com and asked them about bunk spacing for my lift. They got back to me right away with an answer straight from their engineering department.

Edit - in case anybody stumbles across this at a later date, their recommendation for my 2014 G21 was 40” inside to inside. I’d wager that’s a good number for G21s up through 2020.

Awesome, that is a super good tip! I will email them right now.
