3.3L OMC EFI Complete Setup
Powerhead;
3.3L Powerhead built by Sam Jenkins. 12 passes since rebuild. All standard size pistons. Behind the liner porting, DBR Pistons and Sleeves, Matched Etec front half with injector bungs. Jenkins o-ring head frames and chambers. Have different chambers available(120 and 200 lbs).

Adapter Plate;
Sam Jenkins modified 2.7L plate that's been welded, worked, and dry stacked.
Midsection
Baicor DM integrated clamp assembly with horizontal trim arm and tilt arms to accommodate sea star hydraulic steering. They can be removed for wingplate setup. This is mated to Jenkins 16" mid. This setup would use a mercury pump in the boat. It is 62lbs lighter than cut factory setup.
Cowl/Pans;

Cut down and lightened factory pans.
Gearcases; (3 options)
1. 1.78 w large swept skeg

Fuel Delivery;
Holly Dominator double barrel 200gph fuel pump with filters and fittings.
Magnaflow fuel regulator with fittings.
Electronics;
Basically everything needed except for the M&W Pro 16 ignition boxes (I'm using them for another boat). All the wiring and plugs are there for them.
So a complete wire harness system assembled by Sam Jenkins. This includes ignition and fuel/power switches to console. Relays, bus blocks, power cables, ecu hookups, ignition box hookups, ignition box to coil pack hookups.
ECU;
Link ECU Extreme with mounting bracket. All inputs are pre wired to the harness, ignition boxes, and injectors.
Full sequential fuel and ignition capable. Individual cylinder fuel and ignition curves.
Sensors;
Air inlet temp
Water temp ×2 (1 on each head)
Motec Trigger sensor
Throttle position
Water pressure
Motec Fuel enrichment knob
Racepack;
IQ3 Datalogger Dash
Logs GPS, RPM, water pressure, fuel pressure, water temp, air inlet temp, throttle position, all 6 ETG probes.
Power on off switch and two push button switches to scroll through display pages wired to harness.
I will include a laptop with racepak and LINK data uploaded.
This is an easy 400+hp setup with gobs of torque. This setup on 1325 lbs setup (T3) has run 7.75 in 800 Ft with the tight heads. This engine won the Three Lakes Shootout Top Gun Outboard at 110mph on radar, 114 mph on racepak. Feel free to see my videos on my YouTube page under screen name; gemppjr
