You obviously found out what the engine year was. What is the number on the back of your Shamrock? I don't know if there's any difference between mine and others, but the last two digits on my Shamrock serial number are 98, and I bought my boat in 1998.There is nothing obvious like that in my engine model or serial numbers that would indicate the year. I suppose that's coded in, if it's there at all. I think the engines may be stocked and installed a while after purchase, in some cases. It would make sense that they would have a Ford engine in stock over a year.Of course, an Indmar would have been a special order at that time, wouldn't it? My Mercruiser was a special order by the marina, since they were a Mercruiser repair shop.

Your situation does seem strange.Did you ever check your serial number with Shamrock? When it was KCS, I emailed Anita Strand and she sent me all the particulars attached to my Shamrock serial number, just to have all the numbers I could get from them.Charles. All boat manufacturers receive a price break if their material orders exceed certain numbers. Consider Shamrock. They must forecast production a year in advance which put them forecasting 1993 production numbers in 1992. What happened then? First Gulf War!The stock market dropped, fuel prices soared, boat sales slid.

The engine manufacturer probably made them and all the other boat manufacturers a screaming deal on engines so Shamrock loaded up. They then installed their stockpiled engines until inventory was depleted.About 35 - 50% of all Shamrocks have engines manufactured in years prior to the hull manufacture date.

Remember at Shamrock's peak production years they only made 200 boats. To get a decent break on engine prices they at times bought up to two years worth of engines. Plus shafts, props, instruments, etc.Tom. EnginesI thought I might chime in here.

KCS did use Indmar and PCM sea maxx's at the same time for a while in the mid 90's. Randy Moog, My plant manager had a 246 Open with an indmar motor in it. About the years not being the same, it is very common. Two things, one often The boat manufacturer has motors in stock for some time before they get used. Engine manufactureres also often change model years at a different time than boat manufacturers. Thirdly, The inboard motor companies often buy blocks from GM or Ford in large quantities.

This creates a difference in the years from the GM or Ford model years as well. I had a 1997 Mastercraft ski boat with an Indmar LT1, I had some problems and in my search for parts found out that my motor was actually a 1992 block made for a special line of LT1 camaro's. Anyway to make a long story short it is hard to know what year your motor is, but usually it will be different than your year of boat.Bo. This probably won't be of too much help, BUT. My 2003 246 WA was built in 2002 and has a Sea MAXX (ChevyTBI) that was built in 2001.the age of the hull I can varify by the Hull ID #, the engine age I'm basing only on the info packet I got when I purchased the boat new(definately not a conformation.but the engine identification serial numbers match up with one the code used in 2001.If I needed to find out what I had (for part replacements) I would give my engine serial number to Tim (The Engineman) and see if he could help.I'm surprised that Indmar couldn't help you.?Duane.
