    Yes to the question on the anti siphon valve. The ball must move freely and not stick. Be careful removing it. Look inside the hole in the fitting (top part of the fuel pick up tube) it's screwed into, do you see crud in there? If so it should be removed from the tank and cleaned out or...

    two things, the anti-siphon valve can be gummed up with crud inside, the ball can corrode in place but also the part that it screws into (the dip tube or withdrawal tube as it's called) can have a screen on the bottom that can be blocked by crud also. You can rule these out without taking...

    What you can try is to spray the part of the down pipe (below the rubber hose) with silicone, loosen the clamps and spray silicone in the joint between the hose and the exhaust elbow (top curved U shape piece of cast iron) and the hose. Let soak in for a bit. Then try the move the hose up and...

    And getting back to possible exhaust restrictions, it’s easy enough to slide down the rubber exhaust hose and check to see if the exhaust flapper is still in place & moves freely. If it’s missing then it could be blocking the exhaust. All it takes is one overheat in the past. You could also...

    they (OMC) also gave specs for the anti siphon valve and the pick up tube in the tank.

    for the 4 cyls is 3.5-6 psi for the 4.3, 5.0 and 5.7 is 5 3/4 to 7 psi for the volume test, 1 pt in 45 sec or less interesting they give a vacuum at cranking speed test, 9-10" of mercury

    I'm going to see if there's a fuel pump volume test in my FSM. Curious now.

    How do I get that last inch?

    If you look closely, you can see the strap on mine is almost horizontal, I like this pivoting winch bumper design, never have had a problem with it as long as it's adjusted to the correct height.

    I'm wondering if you can have enough pressure but not enough volume. Pressure only needs to be adequate enough to keep the float bowl full, but think about how much GPH increases from idle/low speed to planing/WOT. 2-3x as much.

    I/O (Sterndrive) Conversion to Outboards

    Very interested to see this project progress as somone who has also lived with sterndrives with a boat moored in salt water for 20+ years as well. The boat I have was actually available with outboards although probably few were sold way back then. Actually a 200 Hp 4 stroke would probably move...

    How do I get that last inch?

    That makes sense I can see that the steeper the ramp is the more likely it is to happen. Maybe not as common on roller trailers due to the articulating roller bars….

    I/O (Sterndrive) Conversion to Outboards

    Even New England doesn’t usually get snow till mid to late December….we have not had a “real” winter here in Long Island in 7/8 years. Little snow. We do have a nor’easter coming tomorrow though….

    Bought my first boat to cut, gut and rebuild from bow to stern, including engine. Killed my back and suffered the wrath of the fiberglass demons

    If you own it & someone else gets hurt using it you’ve opened yourself up to a lawsuit. They sue the operator & the owner. PI Lawyers = ruthless vultures!

    How do I get that last inch?

    I think with a single bump stop it should be above the bow eye so it doesn't catch when launching the boat I would raise the winch to try to get the strap level.

    2012 3.0L TKS runs great with muffs, but slow on lake...

    you have enough fuel pressure, but your low WOT RPM might be a lack of fuel volume....that could be a sticking anti-siphon valve on the tank, or a pick up tube that has crud getting pulled against the screen at the bottom of it. Any inboard I think is going to have an anti siphon valve unless...

    Is this engine oil good?

    No one can really say. If you run it do a Blackstone oil analysis and then you’ll know. I’ve had good results with both the conventional Merc 25/40 & syn blend 25/50. I do an oil analysis at the end of each season.

    Engine, Carb or Prop? need suggestions or ideas please.

    that would be great, I do think this size hull did come with that as an option (F/W 201 Liberator used the same hull as the 200 Horizon) could be had with a 454/King Cobra but then I'd have to upgrade the drive too. I think a good running 5.7 4bbl would make a huge improvement and the only NEW...

    Engine, Carb or Prop? need suggestions or ideas please.

    Just thought I'd add: anti siphon valve? pick up tube in the fuel tank? Interested to see what you find out! I have the 4.3 4bbl Qjet as well my 88 F/W H-200 has a 1:68:1 Cobra drive, I have used a 15x17 that gets me to about 4600 and a 15.5x15 which gets me to 5000. Boat is quite heavy for a...

    Bellow condition??

    Triple guard is good as well. In my OMC factory shop manual it mentions using the Evinrude/Johnson/OMC gasket sealer on all bolts that are submerged, but I use em on thermostat gaskets & bolts, anything that is subject to moisture. I have found that both the Merc Perfect Seal and the OMC gasket...
