The efi has its own harness with relay and fuses. It’s connected directly to the battery. Then it has a 12v signal wire to power up the computer. I actually used the choke wire for that job. The signal wire is small like 22ga or 24ga it would have evaporated if that was the problem child.
I’ll...
Had a group out in the water and was underway at 75% power for like 15-20min and the boat just shuts off. Found the ignition fuse (#2 on sea ray 180) blown. Think it was a 15amp? Took me a few minutes to figure out that’s what it was, I installed a sniper efi recently so I thought that was it...
Thanks gents. The flame arrestor is still there but looks like it arrested a big flame at some point in its life and the sticker is cooked.
I ordered a nos #19 wire harness.

I just got done installing a sniper efi on my 3.0l.
Want to double triple check I have the timing dialed in. According to the book there are one of three to use. The trouble is I can figure out what my serial number translates to. It M023026 and that is nothing like the ranges listed.
Also I...
I just got a GLM21450 shift cable kit and I’m a little unsure what these parts are for. The plastic watcher the little metal wire and the orange plastic piece.
The boat is a 2001 I believe the the 3.0 is considered a ‘98 model year? It has the electronic type distributor. I’ve also swapped the ignition module in the bottom of distributor and the pickup coil.
I’ve set the timing per the book. “Disconnect the carb, jump the two wires on the...
Finally got some time to get the boat in the garage. This was an issue before I added the new parts they were attempts to remedy it.
Compression test came back at 155/150/145/150. Oil level is good and looks good not a hint of water.
Attached is a photo of the plugs. Im guessing it was getting...
I have a 3.0 that I’m ready to sink.
Here is where I’m at. New plugs, wires, cap, rotor. New carburetor from national carburetors. New fuel filters, the big spin on one and the little one in the bottom of the fuel pump. New drive unit water pump. Timing has been set by the book.
On my last out...
So I picked up a truck motor to replace a locked up engine on a project I have. It’s a 97 vortec 5.7. The truck motor had 170k on it. Im going to reseal it with a gasket set and putting new rod/main bearings and a new oil pump in.
The old bearings are not terrible but they do have a few...
Thanks for all the info! Especially about the 2 bolt mains. So it sounds like the truck motor is a possible solution.
For the fuel pump I’d wire it like the one on my 4.3 I know there was a lug on the starter for power during crank and I think it had an oil pressure switch for engine running...
