Report
Jeff's Marine sold us a new boat that developed a warranty issue in the first season. They had difficulty with the boat's mfr standing behind their warranty. It took a while, but Jeff's winterized our motor for free, and then had the repair made locally to my satisfaction at Jeff's expense. I was without my boat in the fall, but pleased to now have it was back ready to use in 2022.

I have had nothing but trouble with a Parker 2520 I bought from Jeff's . The boat was repowered with a 357 GM. It was never set up right. The serpentine belt was not aligned correctly---resulted in a broken belt and a tow. The shift of the mercrusier was not adjusted ---no forward or reverse. Resulting in another tow. Motor not aligned---more shop time. U-joints made noise during sea trails---Jeff's said they all make noise. I had to replace the u-joints. Never again!!

DO NOT just let this place do work without giving strict instructions as to what you want. I put my 25 HP ( only 50 hrs) Honda in for idle and new cable adjustment expecting 1-2hrs labor. They did a full engine strip down and rebuild. $621.00 later. No explanation and they broke off the air intake cover left in it in the boat and said nothing. Will not go back. Can't afford to.

I bought a classic 1968 Bertram 20' from Jeff just before he passed away a few years ago and I love the boat. The yard has done a fine job of keeping it serviced, storing it for me and having it ready when I arrive for the summer. Yard specializes in Yamaha outboards -- good stuff!!

WARNING! SHOP SOMEWHERE ELSE.
-- In the fall we traded in a 6hp Yamaha for a 9.9, left a deposit, and was given a receipt by Jeff, the very nice owner.
-- Over the winter Jeff unfortunately passed away.
-- In the spring we came to pick up our 9.9 and the new owners (conveniently) couldn't find our paperwork.
-- They sold us the 9.9 and we left.
-- When we got home we found our copy of Jeff's original receipt. The new owners had charged us $900 more!!!
-- We faxed them Jeff's original receipt.
-- They wouldn't honor it.
-- They wouldn't split the difference.
-- They hung up on us! Do yourself
