If I remember correctly, I thought our stock MC TBI's were the same as an early 90's Camaro.

Hey, I have had a lot of experience in this - and there is hope for you! TBI Injection is fine for the reliability that you're after, and a complete kit with in-tank fuel pump, high pressure lines, filter, and the TBI will run you around $1500 and take a fairly skilled back yard mechanic 8-10 hours to install. Electrical work is also required.
Port Injection aftermarket kits for marine apps don't really exist - you'd have to retrofit from a totalled boat, including HEI ignition and the manifold. It would be a major hassle... The good news is this: I've been through it twice on my last two PS190 boats. The simple fact is that marine carbs aren't built to last 15 years. That doesn't mean, however, that they aren't any good. If you want an easy, fast, painless solution, I'd go down to the local NAPA store in your town, and have them order you a brand new HOLLEY Marine carb for your boat (4000 series, probably). They retail at MC dealerships for $730, but go for $509 at NAPA! Trust me on this one - I've done it twice, and my boats start on the frist turn of the crank, and run like a fuel injected boat. Most people can't believe how well my boats run... Good luck! TIM |

Oh - One more thing - VERY IMPORTANT!!!!
NO Carb or FI designed for street cars is either SAFE or EFFECTIVE on a boat! Please don't try it. TIM |

The TBI system on the boats is really the same as what was used on cars and trucks. There's a septum in the intake manifold and one injector feeds each. It's not an Indmar system, Indmar takes an existing one and adapts it for marine use.

Any ideas as to what other applications this pump may have been used in??? |

The only question that I have with using a car multiport injection system ona boat would be the 02 sensor. I know that Ford ECU's take their main readings from the MAF and O2 sensor wouldn't a wet exhaust system corrupt the reading from the 02 sensor? And make the engine think its running rich?

A really easy way to upgrade to EFI is to buy a GM Performance Parts crate motor, like the 350 RamJet. 350HP/390Ft-lb of torque, it uses the same ECM and any GM dealer can service it when the warranty is still in force. The thing about MC- they calibrate teh engine to the boat, not a generic weight load. |
