The mechanic at the highway construction company said the LT1 outlasted the others 2 to 1. Several were made by Lombardini, others were Lister-Petter AC1's and 2 were LT1's. I bought about a dozen assorted diesel engines from scrapped arrowboards.

The Lister-Petter engineer also mentioned that he could tell that my engine was built for export (from the UK, that is.) Lister-Petter probably uses a different numbering convention to differentiate engines intended for domestic or export sale.Īrrowboards powered by diesel engines were obsoleted by solar powered units in the mid 1990's. It's reasonable for Lister-Petter to have built 732 of this model in the 2 - 3 years (2 years = late '77 to early '80) of production.īut I'm not saying you're necessarily wrong. In this case (LT1) the engine was introduced in 1977 and the unit in question was built in 1980. Date codes aside, don't you find it strange they Lister-Petter would only allow for a 3 digit serial number? You'd think they'd figure on building more than 999 engines. A friend gave me an ST-1 with a date code of '35.' I remember him buying the engine new in 1986. I though it strange, for example, that it was necessary to add 50 to 'year' to arrive at the correct figure but that's appearently the Lister-Petter way. The gentleman from the engineering division explained (in a delightful British accent) the numbering system to me. I got my information from Lister-Petter's US operations in Olathe, KS.
