    resurface access hatch

    The lids on my access hatches are oxidated. They are fine structurally. They get dirty very easily and are porous. Can I do something about this? I was thinking of white vinyl paint...?

    Seastar steering issue

    I have a 2005 19' Center Console Cobia with a Yamaha F115 and Seastar hydraulic steering. Boat has under 200 hrs so it hasn't been used much before I got it. It seems to turn right with no issues. Sometimes turning left, it takes extra turns of the wheel. Sometimes the engine won't move for a...

    Yamaha F115 low RPM's at WOT

    2005 f115 on 19' Cobia CC. Engine has less than 200 hrs. I bought this boat a few months ago. 1st time I had it out it would reach 6000 rpms easily and cruise about 33 mph with the black ss 17" prop. I borrowed a 19" aluminum and got about 35mph at 5800 rpm but seems to feel worse after a few...

    3.0 water in oil

    I have a 96 17' bayliner with 3.0. I am getting water in the oil. I flushed it real good 3 times with diesel and changed the oil twice. I was hoping water got in from being uncovered according to the previous owner. Spent the day on the water and put 20 miles on it and parked it. Today I drained...

    steering stiff, cable removal

    Hello. I have a 96 bayliner 3.0 alpha I gen II without power steering. On the trailer the steering seems fine. In the water under load it takes two hands and is very stiff. I removed the cable from the wheel and the wheel moves fine and hooked it back up. I removed the pin from the...

    water inlet tube drips slowly... is this wicked bad?

    While dropping in my port 470 3.7 in my boat I accidently hit the water tube comming off the gimble housing on the inside transom. I took extra care to observe any leaks from there when I launched the boat. Sure enough it drips a small drop every 5 to 10 seconds. My temp is great on the engine...

    Mercruiser 140 in saltwater ok?

    It looks like I will be moving within six months on the coast of NC. There is not a lot of freshwater there. My boat is a 1987 19' CC with a 140 Mercruiser. Everyone tells me to get rid of the boat and get a new one when I get there because salt water will destroy it. I like my boat. I don't...

    Water and exhaust while idling

    While idling on muffs, should their be equal amounts of exhaust and water coming from both sides of the bottom outdrive? It is lacking WOT RPMS by a few hundred, and I just thought of this. I replaced the exhuast flapper when I changed the engine b/c it was burnt up from a bad impeller. The...

    What is this on the carb?

    I asked a week or two ago with a good description, but no one seemed to know what I was talking about. I came across the picture, but still doesn't say what it is. It pushes down on the power valve. So my question: What does it do, and what does the power valve do? Mercruiser 3.0 carb

    Boat handling? Normal?

    19' Glasstream CC with alpha one and 3.0 mercruiser. I am begining to think there is something wrong. Is it normal for a boat to pull HARD to the left? Idling in gear, it will creep to the left. I can let go of the wheel for a split second to grab something before having to grab the wheel to...

    EST Ignition

    3.0 mercruiser alpha 1. WOT about 4000 rpms... I just can not seem to get WOT RPM's, and I am starting to blame the EST ignition. Has anyone had any real experience with them vs the points? New fuel pump, two rebuilt carbs with same results, good compression, good cap/rotor, new plugs. I even...

    Will this restrict WOT?

    I am putting another intake on. It ran awesome the way it was, but I guess I am not reaching WOT with 4100 rpms. Compression is good. Just a rusty crusty intake and ports!

    Another prop question - looking for speed

    I have a 19' CC with a 3.0 Mercruiser Alpha 1 outdrive. I know it is a little engine. It has "3x14.8x19R" stamped on the prop. This boat gets out of the hole really good, but tops out at about 31 - 34 mph pushing about 4100 rpms. I am willing to sacrafice a little out of the hole for a bit more...

    compression test #'s - good?

    1. 170 2. 164 3. 159 4. 175 In my mind, it's fine, but I am no expert on these motors. Opinions?

    rod with spring in carb

    What does it do? It is a rod fixed into the upper carb plate. It is solid, but has a spring with two tiny clips that looks like nothing but spacers. It looks like it is seated at the base of the float bowl pushing on a brass plug with a nipple. I pulled it out of the upper carb part, and it has...
