251-251GTX-253-259-270

Well-known member
Sclemons asked about the differences in the model years of the 25 Convincor line. I thought I would start a thread with my very small amount of knowledge and the help of old Powerboat articles. Maybe Mr Kip, Haftoo, or othe forum members can fill in the blanks.

Checkmate introduced the 25 Convincor OB in approx. 1983 and the following year the 251' Convincor IO debuted. The 251' was listed as 25' 1", 90" beam, 23.5' deadrise, 3,700 lb weight and rigged for a TRS drive and transmission. In the following years the hull was tweaked: the chines were widened and turned down 6 degrees and the keel pad went from 12' to 16' deadrise to soften the ride.

The 251 GTX appeared around the 1989 model year. While the hull was pretty much the same as the 251', the GTX offered several new styling changes. The deck and dash were totally redesigned. The windshield rake modified. The 251 teak interior accents were replaced w- lexan and formica. Cockpit space was also improved w- the new deck and changing engine packages from the TRS to the Bravo drive. Checkmate also offered the 251GTX again in the late 90s as the 251 Classic.

In approx. 1993 the 253 Convincor replaced the GTX. This model is listed as 25' 3", 3,750 lbs, 99" beam, and 24' deadrise. I beleive the main changes were the extra 9" of beam and widening the outboard strakes to allieviate the 251 chine walking (?). The 253 also sported a new deck and dash. The cabin door was widened and now slid into the bulkhead.

The 259 Convincor appeared around 1999/2000 model year. It is listed as 25' 9", 103" beam, 4,000 lbs, and 24' deadrise. The main changes were the extra 4" of beam and a new dash. I am not sure if any changes were made to the bottom.

The 259 changed to the 270 Convincor in the 2000s when manufactures started to include swim platforms in the LOA. Checkmate also offered a 270BR.

Please add any other information on the 25 Convincor line (or correct my information).

An easy way to tell a 251 from a GTX is to look at the dash. The 251 will have an upholstered dash pad/grab handle on the passenger side. The GTX does not.

An easy way to tell a 253 from a 259/270 is that the 253 will have a "style" line on the side of the hull where the 259/270 is flat.

I was seriously thinking about the 253 for my next Checkmate. Over all a slight better choice than a 251 unless the price of a nice 251 is a real good one. Must wait a season or two for this to happen.

I will look to the membership to see what is available here first.
 
after owning both the 251GTX and a 253 will say the improvements are great with the 253 all around...well worth the xtra $$$ great info SCT !!!!
 
Did the 242 become the 260?

Since my 253 is a 93, I wonder if mine is/was one of the first made.

Ok Shannon...so how much info can you dig up on the 2800SX Outboards?? To my knowledge they were not in any of the catalogs (except for a pictorial poster which I have)...hull weight, beam, deadrise, years built, etc.;)

So far we've rounded up 7 of these boats in the past year:
1) My 2800 "Ashland" special edition
2) 2tonChevy's Red race boat
3) Bravo1's unfinished but newly painted "Bud" boat.
4) Burke's (from our site) pleasure boat 2800
5) Red race boat that went to Japan
6) Light Blue 2800/Johnny Rudes that was for sale in New York (rough)
7) White 2800 that was for sale in New Hamshire
