    Grew 237 Prop Question

    Southern Georgian Bay (Severn Sound) area. Boat may be a 35 year old boat, but Grew boats were built in Penetanguishene for Georgian Bay waters and boat is in perfect shape for it's age. Engine only has 650 hours on it.. The boat that I was crewing on before they retired was a 1978 Grew 255...

    Grew 237 Prop Question

    That is what I was thinking, 34-3500 should be where I need to be. Drive is trimmed right down at throttle down for getting on plane. I have to raise the drive trim as the boat starts to accelerate even before on plane in bursts or it will not even get out of the hole. Once on plane, I have...

    Grew 237 Prop Question

    WOT is still 4600. That is what is confusing me as it is right in the middle of the 350's recommended WOT range. However, the boat acts like a slug in the water. Hole shot takes forever with 4 on board, and to get 21 knots out of her required 4000 RPM, and that was on flat water. However...

    Grew 237 Prop Question

    Thanks for the information. Circumstances have prevented me from trying out different propellers to date. Over the weekend I did confirm that the propeller on the boat is a 15 x 17 Quicksilver 3 blade. With 4 people on board, 4000 RPM is required to get the boat up to 21 knots, and takes...

    302 888 Mercruiser smokes during startup with choke on

    Hi All, I am having a problem with my 888 Mercruiser(302 Ford Block, 188hp). When I start the engine up from cold, there is a lot of smoke coming from the exhaust, and the engine runs rough. This only occurs on start-up from cold with the choke closed. As the choke opens up (electric choke)...

    Mercruiser 888

    Hi all, I think that I have my prop issue solved, now for the next conundrum. I wanted to make sure that the lack of RPM is the prop being overpitched and not that the engine adjustment out a bit. I checked the dwell and it is at 30.1 degrees, so that checked out alright. Next I looked on...

    888 Mercruiser, 26' Bayliner

    Hi Guys, I have a 1979 Bayliner Saratoga 2550 with a Mercruiser 888 power plant that we just bought this spring. After having it out this weekend, I realize that the boat is obviously over pitched on the prop, currently a 19 pitch prop. WOT is about 3100 RPM with the boat trimmed out as best...
