Glad you got it!
Since you have an I/O it's highly advised to keep the anti siphon valve. Yes they can cause trouble but if the fuel line leaks between the tank and the fuel pump and if that fuel line drops below the level of top of the tank the fuel can siphon out of the line into the bilge...
That’s the fuel pick up tube also called the fuel withdrawal tube. Use penetrating oil, time & patience. Do not force it work it back & forth just a bit spray more penetrating oil, get it to move a bit more etc. Dang aluminum!
Here's one on my V6 4.3 Cobra. middle pic is new
top & bottom is burned up from overheat
had to pull the outdrive to get all the bits out lol.
This an OMC but Mercru is similar...
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...
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
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.
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...
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….
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….
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!
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.
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...
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.
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...
