    2009 150HP Optimax willnot rev up

    I am working on the subject motor. It will accelerate normally to about 2000 RPM, and try to climb on plane. It then stumbles and the RPMs drop back to idle. We have changed the on motor water separator and the fuel is fresh. We are leaning toward a fuel system problem in the motor. Anyone...

    Pretty Good day yesterday

    Sunday 8 Dec looks to be a pretty good say, for this time of year in the northeast. I finished the maintenance on my OB, put the ridge board and supports for the cover and got the cover on and tied down, just as it started to snow. It was the same storm as DC/Baltimore/Philly. Did some other...

    Missing telltale plug on Ocean runner V4

    I saw a guy running a mid-late 90s 115HP Oceanrunner (60*) without the flush plug. There was all kinds of water coming out. I had thought that needed to be in place except when flushing with a garden hose. My V6 motor of the same type has a plug suitable for a quick connect hose fitting, and...

    Highest performance aluminum propeller?

    I am currently running a 21P Turning Point Hustler, on my 16' Avenger/135HPV6. It is vented and has pretty good rake, and I can just touch 6000RPM/60MPH. Since Hurricane Sandy took all my other props, I ought to get a spare prop. Is there a higher performance prop than the Hustler, for my...

    Boat Trouble in "3s"?

    I was out in the speedboat, likely for the last time last Thurday. Pretty flat conditions, pretty warm. I make a turn at low speed, or should I say I try to make a turn at slow speed. No steering....Cable just snapped. Never saw that happen before. They usually seize up first. So turn the...

    Do you need to carry a spare modular prop hub?

    I have a Turning Point Hustler prop with a modular hub. If I was to hit something could the hub break such that I would be unable to limp home? Related question: Standard prop hubs sometimes start to slip, w/o warning. Do modular hubs do the same?

    Does Ethanol remove water from the separator?

    I know that ethanol in gasoline will absorb water. Suppose you have some water in the water seperator, and you run several tanks of water-free E-10 in the boat. Will the gasoline + alcohol actually lessen the water trapped in the separator? It sure seems like it should.

    4 Blade Turning Point Hustler prop with two different kinds of blades

    The new 4 blade Hustler prop has a pair of cleaver-style blades and a pair of progressive rake blades. I have a 16' Avenger with a 135HPV6 Merc. I had planned to use a 3 blade Hustler, as I think it is about the best non-SS prop I have tried. Is the 4 blade better or worse for my...

    And a lot of other things, I might add. Is there a legal, but free .pdf source?

    Did Wallyworld change their supplier or did I get defective TCW oil?

    I opened a new gallon of SuperTech TC-WIII oil today. I had used the stuff for years and expected to see the usual royal blue oil color. What came out was medium green and seemed thinner than the usual. I put some of the green and the blue into identical containers to see if I could detect...

    Does Saltwater preserve wood?

    Some years ago, I visited the US Constitution. For those who do not know, she is the only wooden vessel still commissioned in the US Navy. The tour guide made a point to say the rain water rots out the ships timbers, and salt water preserves them.

    Anyway to run a prop from a 4-1/4 gearcase on a 4-3/4 gearcase?

    I have a nice 21P Rapture that I bought for my Merc IL6. The IL6 blew up, and now I have a Merc 135HPV6, which has the 4-3/4 gearcase. Is there some sort of adaptor I can get to use the Rapture? I tried it w/o an adaptor and it was like driving a car with a slipping clutch....

    What is 2 cycle oil pre diluted with?

    A lot of 2 cycle oils claim to be pre diluted for easy mixing. Some are specifically listed as not diluted. What are the oils pre-diluted with? Alcohol? I presume the pre dilution does not affect their lubrication abilities. Another question. Did Mercury make 12 oz oil bottles in the 1970s...

    Can you believe it two

    On the same show, they are selling a Diesel fuel polisher. This is a self contained pump/filter that uses magnet and fuel "swirling" technologies to keep older diesel fresh and clean up low quality diesel. It draws diesel from the tank, polishes it up and returns it to the tank. The host says...

    Can you believe it?

    I was just watching "Pleasure Boating" TV show. They showed a custom-built boat, with some unbelievable features. It looked to be 18', and built in the style of those 1950s Chriscraft speed boats. Bench seats front and back, mahogany deck, with the yellow lead seams, and a blue FG hull. It...

    Is there a RPM limiter in my Merc 135V6?

    My Seloc manual doesn't seem to know. Does the Idle stabilizer also limit RPM? Do the switchboxes limit RPM? My speedboat runs right up to 6100RPM or so, with lots of pep. I was wondering whether something was limiting the RPM.

    Source for Marine Carpet?

    With the economy being down, it appears thet the Home Despot and others do not stock much indoor-outdoor carpet. Anyone have a good source for indoor-outdoor carpet? I need an 8X8 piece.

    What happens when you add more e10 fuel to e10 with phase seperation?

    Ok, lets say you have a gallon of 10% Alcohol-gasoline mix, and it gets enough water into it to turn cloudy. Now you mix it with 10 gal of e10 without any water it. Does the cloudiness lesson? Will the water be absorbed by the rest of the e10? Anybody ever done this experiment?

    New Wakeboarder = Dumb Question

    I bought a wakeboard for my son for Christmas. It is a Hydroslide with a wrap binding. I am familar with Salom Ski wrap bindings, but this one has two 15" long heavy rubber straps on the outside of each binding. There is velcro all over the bindings, but it is not obvious if those straps...

    Was there a HP competition Merc vs OMC?

    I know Johnnyrude developed the Fat-Fifty in 1958 as a stepping stone to the 60HP, 70HP, 80HP and eventually 90HP V4 motors. What was Merc doing at this time? Was OMC playing catchup or was it leading?
