    1977 Ford 460 ignition

    Working a buddy's 1977 Tahiti, 460 Jet and found a marine distributor with points and condenser inside. Has two clips on the sides like the old Fords, but the rotor looks a little different. Wider at the end away from the contact. This is a Berkley Jet, and does not have a covered engine, water...

    5.8l efi idles too fast

    So the first pic is a connector by the front of the engine near the thermostat that I can't find a connector for, but it sure looks like it should be plugged into something. The second is a plug in the pink wire between the dizzy and ECU? I think I'm supposed to pull to check base timing and...

    1996 Four Winns 5.8 Duo drive Fuel pump location

    Scott, thanks for the education, I see there are differences between automotive and marine stuff. Maybe I should be working harder to find the idle issue on my EFI. I'm just at a bit of a loss as to where I go from here. I suppose pulling the lower intake and looking for possible air leaks is...

    5.8l efi idles too fast

    Hey Chris, can you tell me where the test port is? And what the OBD I looks like? Thanks. I did get the manual to download.

    5.8l efi idles too fast

    I didn't see this until now, Thank you so much! Still having issues with the idle. Was unable to find more vacuume leaks, but have the gaskets for the lower intake manifold. Was intending to swap out to an Edelbrock with a Holley, but if I find issues under the lower section maybe I'll see if I...

    1996 Four Winns 5.8 Duo drive Fuel pump location

    Replaced the IAC with new, no difference. Are you saying that corrosion will be an issue with aluminum? Or is that a salt/brine water issue? Not heat exchange cooled. A 351 C.I. engine at 6,000 RPM will displace 610 CFM at 100% efficiency, which nothing naturally aspirated will. Chevrolet ran a...

    1996 Four Winns 5.8 Duo drive Fuel pump location

    Opps, brain fart, yes it is a V/P. It is EFI at the moment, and runs perfectly except for not idling down like it should. I don't think there's a "top" for it to leak fuel from. Yes if it were Carbed and had the EFI pump it would surely leak fuel and flood. The EFI pump should have an electrical...

    1996 Four Winns 5.8 Duo drive Fuel pump location

    I am looking to swap out the fuel injection system on my 5.8 Mercruiser (Ford) for an aluminum manifold and a good old fashioned Holley 600. I just can't get it to idle down below 1100 RPM. My question (s) are where is the fuel pump located, assuming I'll need something with a lower pressure...

    Fuel tank mounting

    I'm working on a 1996 Four Winns 220 Horizon. It's got a floor panel creaking when it's walked on. I bought plywood, thinking it must be soft, (and a couple other projects) and after removing the panel I find the supports that go across the fuel tank are cracked. They cut a V notch in the bottom...

    5.8l efi idles too fast

    There is a stop screw that keeps the air valve from sticking closed, the valve closes well against the stop, but the idle is still erratic and around 1200 rpm. Even if I back it out, with the valve closed tight. Shifts easily in and out of gear out of the water, but very had to get out of gear...

    5.8l efi idles too fast

    Are you talking about under the Upper Manifold? Under the Throttle Body? I will get some brake cleaner, (easier on paint) and spray selectively around that area as well as the base of the upper intake. I'm familiar with the OBD II test ports on autos, but what do I need, and how do I connect to...

    Thanks Scott, I can only find the parts diagrams there, no service info

    Anyone know of a service manual for this boat/engine available? What do you guys use to look for intake leaks?

    5.8l efi idles too fast

    I have a 1996 220 Horizon that idles around 1200 rpm. Somewhat erratic and slow to return to idle after revving or running at speed. So far I've changed the IAC valve, the TPS adjusted the stop screw to just the point that the butterfly does not stick, and resealed the two throttle body gaskets...

    Exhaust pieces and parts

    Thanks for all the good advice and tips. Lou C, I once watched a short block on a test stand being spun with oil pressure to do a break in. At around 600 rpm all the pistons looked like they were all at the top of the cylinders. At 1000 rpm you could push straight down with your finger on top of...

    Clam shell cupholder drains

    So turns out both the small ones are broken. One is just a hole, the other is just what's left of the backing. These do not have screws to mount, like the chrome one in the third pic which I think is the anchor locker drain. Sorry the pics are not better. As stated I have searched the web many...

    Clam shell cupholder drains

    Not a holder, just a clam shell shaped through hull drain for the cup holders. I'll get a pic of the damaged one today.

    Clam shell cupholder drains

    My 1996 Four Winns 220 Horizon has small clamshell drains on each side for the cupholders that are just in front of the windscreen. One is broken off on the outside of the hull, and the other is dented. I have searched around the ol' interweb unsucessfully. Does anyone have a part number or a...

    Steering leaks

    So here's the update. Seals for the older style cylinder are not available. Five Star Marine does not offer any service for them. The new style is a very nearly direct replacement, but for the clevis pin to attach the steering cable being a tad short. Half a cotter pin hole. Sourced a remanned...

    Exhaust pieces and parts

    Sure seems to be true so long as one has the ability and the time. That is an advantage of being retired and having tools and a place to use them. I wonder if I should let the previous owner know what kind of issues I found, not that I'm unhappy with the deal, but so he might be better informed...
