    Changing a 1989 4.3 liter gmc block to fuel injection

    Yes. A 4.3L would be very possible. There would be bugs and hurdles until it was ironed out though. Especially with an OMC shift interrupt system, since EFi is very good at holding specific idle rpms. It would have to be triggered with the ECU. I’ve been looking into EFI for my 3.0l as my wife...

    OMC 140hp with 400 stringer sterndrive lots of questions!

    16’ SS with 140hp will fly. The guys who know more about them than I do will chime in I’m sure. If it’s still serviceable you’ll find what you need to keep it going. If your boat needs a transom, it might be time to seek out a rotted 3.0L mercruiser boat and convert it ( Late model Volvo just...

    Affordable fuel injection intriguing

    I sent Holley a message seeing about what distributor I could use to make it work. We will see what they say. Affordable also sells Sniper and they say they will pre tune the unit. But they don’t list any cost

    I’ll have to dig and look into things.

    Affordable fuel injection intriguing

    So it was a fuel only setup.. Having ECU control timing is probably less of an issue than I make it and it would most likely be fine, especially for a little 3.0l

    WiFi Security cameras

    Are you talking like offline mode? If that’s what you are thinking, a camera with AP mode will work. I’ve got a couple Ampviz cameras set up for my sister in law in her cow barn. Barn is 120’ from the house and gets enough signal to work reliably. Any farther than 100 foot or so is really...

    Affordable fuel injection intriguing

    Pictures of them online show Rochester products but some of them also have a Mercruiser emblem cast into the base. Since fundamentally they are identical, it would wonder if a little detail like that mattered that much

    Affordable fuel injection intriguing

    Holley sells distributors made for the Sniper that are adjustable and can be phased for the sniper so that the sniper can control the timing.. I have a 3.0L so no such distributor available. The Delco EST will do the trick if it’s tinkered with and the module bypassed. It is basically a TBI...

    The TBI modules are like $50 at a parts store

    Affordable fuel injection intriguing

    This is kind of my thinking. I know that they use rebuilt OEM GM TBI throttle bodies, so it would come down to IF GM/ Rochester actually ever certified the TBI model they use for coast guard compliance, but I knew he was doing a marketing ‘dance around the question ‘ As for the Holley, that...

    Affordable fuel injection intriguing

    I got an answer back from them. They install an automotive module in the Delco EST distributor, which is actually for TBI trucks. Makes it so the ECU can control timing. He said the shift interruption will still work and he said that installed correctly it will pass a USCG inspection. He didn’t...

    3.0 MPI distributor? Specs needed

    I figured this out while looking into FI for my boat. The guys at Affordable Fuel Injection told me that they swap out the Delco EST module for a GM car module so the timing stays locked on their marine kits. I had an epiphany moment and looked up the module for a ‘95 Chevy 1500 (TBI), and...

    First boat! 1989 Quantum 1800xb Force 125

    plan on the stringers. 95.9999999% chance they are rotted as well. I recently cut up one of my parts boats, which was a Four Winns Freedom 160. The boat was rotted from about the windshield back. Very little solid wood, and before I bought the boat, the previous owner was running it in the lake

    Affordable fuel injection intriguing

    I think Affordable uses genuine GM TBI throttle bodies and GM sensors. I wouldn’t hand my cash over without at least a few calls/ emails. I looked a little bit into the Sniper EFI but it always comes down to something isn’t quite right, or there’s a weird surge with the shift interruption or...

    I thought the picture looked like a GM ECU. That could be one up for reliability

    Affordable fuel injection intriguing

    I just ran across Affordable fuel injection for marine engines. I’ve known Affordable fuel injection existed but never paid attention. Shows about $1,500 for a complete kit, which doesn’t use an O2 sensor and a video from 6 years ago suggests they use Mercury marine ECUs with custom software...

    Literally my season hasn’t started yet. I’ll hit the lake with the little outboard runabout next weekend. I’ll run it till November

    Tin StarCraft would be my suggestion. You’ll go as fast as the powers that be want you to. Hp limits have to do with shore line erosion

    Mercruiser 120 Coil and Resistance With Points

    Oddly enough you can go to Napa and ask for a coil for a 1965 Chevy II with 153 cid 4cyl and you will get the right one
