Ok, I'll bite.
WHY are you running an electric fuel pump??
I was running a mechanical and an electric together. When the boat sank on the trailer the electric one got destroyed and the mechanical one is due for a rebuild. So instead of rebuilding and buying a new $300 pump to fix what I had, I bought a Weldon pump. Number one reason for the Weldon is, it's made in the USA. Number two for the Weldon is, I'm planning on converting to EFI soon. The Weldon works for both carbs and EFI with only a regulator change. Number three for the Weldon is, it's warrantied for life.Quote:

Wife jumps out, runs to get the trailer, I head to the ramp. There was so much water it the boat already that the blower belt was throwing it around like a geyser. Motor stalls, my friend was already there following me around to the ramp, so we tie to his boat and he stars towing me. His boat is a jet boat and those squirt pumps can't pull the weight for shit so we couldn't get it on plane to have the water start to drain while we're moving. It just kept filling more and more. wife gets the trailer in the water buddy does this rodeo maneuver and swings me into the the trailer. We get it cranked on and down she went. Filled that fucker with water all the way to an inch under the breathers. That was the third time I've had an issue with it, so now you understand the 2 stage pump and filling the transom and merging the exhaust.
Efi, yes Efi. After the summer I will be making a hilborn style 4 hole injector setup with progressive linkage to each butterfly so it will be tunable. Each butterfly on it's own shaft and adjustable for travel.Quote:

:popcorn:
There are already mechanical injection setups converted, I know this. However the butterfly's still are on the same shaft and not very drive-able. So whats the point of EFI with these setups? If each butterfly is adjustable to the amount of travel it has and when it starts opening then it makes sense. You can control your CFM's and when they flow. And yes I know, why go through all the trouble when you can just bolt a couple 4150 throttle bodies on there and be done with it? Because they're not old school cool, that why.Quote:

Did you say daycruiser? :DQuote:

Yeah. Only 23 ft. The same size Dave equips each boat with, for ship to shore use.:speechless-smiley-0Quote:

Either way they are still going to be thru-transom and above the water line. If I merge them, they will end up with one oval shaped tip about 4" x 7". It will sound bitchin merged but it might be a bitch to work on. Opinions................

It will look a little unique, but it won't much different unless you merge them pretty close to the collector to increase the length of the single pipe. This didn't sound any different than without the merge oval. It doesn't matter how much pipe you have before the merge, if the merge happens near the end of the pipes, it does have much effect on the sound.
Now the builder of these ended up building a set of 180* headers to use with these, and that did change the sound, but it wasn't due to the collector.

Pump and cover came out real nice !
So Bob, where can I get a hold of one of these little dolls???? building some 180's myselfQuote:

or combine them into 4into2 and split them like the new vette setup
