    Full StarFull StarFull StarFull StarFull Stariboats came through again!
    by Lauris from Gonvick, Minnesota on September 19, 2015
    I was beached by a worn out alternator on my MercCruiser engine. I contacted iboats ordered a replacement that was to be shipped in two days. They did not have it in stock and it was back-ordered. (This could take weeks to get). Iboats came through in just a week with the new alternator delivered to my door and I am happily back on the water again. Not only did they respond quickly, but the price was the lowest of all the places I checked. Thanks iboats!!

    Q:
    WILL THIS FIT IN A 1994 FOUR WINNS SUNDOWNER 195, 5.0 LITER 190 HP ? IT IS NOT FUEL INJECTED, CARBERATOR?
    A:
    It will depend on the engine manufacturer as well. If you can provide that along with a serial/model number, we will take a look for you.
