Hi Everyone,

I was wondering where to find the engine serial number on my 1989 Trophy 2459 Offshore?

Thanks,

If I remember correctly, the number is stamped on the port side of the block..You have to get down under the manifolds to see it. If you have a flash light and a mechanics mirror you may be able to see it without all the contorsions. It has been a long time since I looked at one. Your cylinder heads also have numbers too but they not the same as the block. If the engine was a reman, they still put manufacturers number on the block That might be a plate instead of a cast number.

Thank you, I will check these areas. It is the original engine and heads.

Here is another photo of a block number and Mercruiser number. It all depends the year. Mine was port side under, yours may be different.

Sorry to sound ignorant, but I just acquired the boat from my dad and it is 3500 miles away. I am unable to get the information from my dad, but one of his friends told me it's a 351 ford 4barrell.

A 351 is a 5.8L. Does anyone know if this year and model had that option? I have the same year and model, and while his was built in FL and mine in WA, I would think they would both have the same 5.0L. Mine's been replaced, but the OP says this engine is original.

Yup, back in 89 OMC did use Ford 351 5.8
