When did the LT-1 show up?

I have an 84 MC with the 351w, but also a '96 vette with the LT-1. What years did MC install the LT-1? Did they still use the oem "optispark"? Were these motors reliable in a marine application?

LT-1 first year was in 93 in the Limited Edition boat they made 25 of. In 94 the 275hp fuel injection was the standard equipment with the LT-1 avalable as an option. The first couple of years of the LT-1 had several ECM updates.

The LT-1 did not use the GM Optispark system. It used a very reliable distributorless ignition that came from tha Cadillac Northstar Engine. The LT-1 was a great engine. It was in production at Indmar from the 1993 through the 1998 model year. A few were built in 1999 but the standard MPI engine in 1999 was the LTR.

George, I think the LT-1 was an option apart from the 25 190 Limiteds they released. I saw a 1993 S&S on ebay recently that was sporting a nice LT1.

To me, this forum is about love of inboard boats. It is about the sharing of information and, on a good day, some humor. It is not about post count, brand of boat, or any other superfluous labels that lend themselves to a false sense of superiority. Please, respect one another, try to pass on accurate information, and keep your eye on the ball.

East tx skier,

You are correct. I have a 1993 190 with an LT-1 and it is not a special edition. I think that just judging by the number of LT-1 overheat questions; there had to be more than 25 1993 LT-1s on this site.

I stand corrected. I do know of one S&S in red that had the LT-1 It was the first red S&S to come off the line. It lived in NC I'll see what my brochure says in my spare time.
