Hey guys,
I need your help. I'm trying to replace the raw water pump on my 1976 X-18. It has a Mercruiser 280 TRS drivetrain with the stock small block Chevy 350 V-8. I believe the raw water pump is a Jabsco and is the earlier of the raw water pumps used on the TRS series engines
I have been on the Internet and the word is that the earlier pump is no longer in production. The replacement pump is about twice as long and was used on 330 TRS's (Chev 454s). The customer service tech I'm working with is trying to get me to convert over to the new series pump which means I would need a new pulley, bracket, and most likely belt. He's saying it would be considered an upgrade.
The point is that I need a one-for-one swap, not to convert part of my cooling system.
Any sage words of advice? See the pix. The nasty shot is the pump needing replacement. The other is the new series pump (~9" long)
Thanks in advance!
