Hey fishinwrench mercury question

[rumrunner]

Do you know if Mercury kept making 2.0L or 2.4L moters past the eighties? Someone is telling me a 1997 150hp block I have is a 2.0L. I thought Merc switched to the 2.4 in the early eighties, then switched to 2.5 about 1989. He is saying Merc kept making different size V6 blocks.

Thanks!

I did some digging and found the answer.  It was way more complicated than I realized!

It is confusing.  The 2.0L was the original XR2  But before that you had the 2.4 BM which was a chrome bore powerhead with vertical reeds.  Then along came the 2.4 Bridgeport (steel bore, horizontal reeds, and among the most sought after of all the Mercs).

Then came the basic 2.5L, and then 2.5 with boost port(XR4)......then back to the original 2.5 (XR6)......and then onward with the 2.5 as an EFI.  

It's enough to make your head spin.

Wrench how did you keep all that straight when you can't even decide which fly to use.

My very first V6 overhaul was a 2.4 Black Max chrome bore.  It lasted just under 4 years, and then detonated #4 while trying to beat a Charger/Yamaha to Cole camp creek.   Rebuilt it AGAIN, and a year and a half later it broke the crankshaft during a hole shot.  Rebuilt it a 3rd time.....and sold it to a poor bastard in Wisconsin before it could go down again.  😅

That is his rub with Merc's.  Spends too much personal time on them.

As far as I'm concerned Wrench is right.  Mecury is like Trane heating and cooling equipment.  They don't give a **** about the customer.  "We have your money now, just go away"

Pretty much.   

It isn't the motors that I hate...... it's the way they operate as a company.   It's just ROTTEN.      And the loyalty that so many folks have for them is confusing to me,  because it certainly isn't deserved.

I hear you. I found the mercury fans of those years believed they were alot faster. Or sounded cooler. Trying to figure out model numbers and part numbers on older stuff is a crapshoot at best. I didn't realize they kept making 2.0L 's for so long. All the common parts with the 2.5L fooled me. I guess the main difference is the bore. Thanks as always!

They ARE fast.....if you can get out of the hole.   Low end torque (needed for a snappy hole-shot) is their weak area. 

Once you can get craaaawled out of the hole, and the bow finally breaks over...... Then she'll scream.
