    We have used J&H for Service (Ranger Tugs R27 and trailer, aluminum Pioneer) over the past 12 years. I have also ordered parts several times. They have been very accommodating and Fred in parts is simply the best resource. Believe what he says. I just ordered a replacement seawater impeller and it cost $2 more than it did 5 years ago! I thought with all of the Covid related “inflation” they would charge me much more. I will keep using them and recommend to a friend.

  • Cory P.

    Excellent workmanship and customer service. I have worked with several boat mechanics in Nor Cal and Eric is the best! Highly recommend.

  • Michael M.

    They replaced one of the engines on 36′ Silverton. Although they had some hick-ups along they way that were really not their fault, in the end the boat runs fantastic! Thank you Kelsy!

  • Bruce S.

    The crew at J & H were relentless at solving the issues that other shops could not solve. Thank you guys for your great service.
