just picked up an 89 242LS. Love the boat absolutely awesome ride. However im noticing the temp is a steady 160. All my previous boats had small block 350's with 140 stats and rarely went above that. This boat has the 454 mag mated to a bravo one. The previous owner said the temp was always at that. Should i replace the pickup in the drive and throw a 140 t-stat at it or is this normal?

nope , late models 454 have 160F thermostat

KMONEY....think you are right where you should be at 160. Throw up some pics of the new ride!

My 89 Sr1 with twin 454's run at 140* all day long

Carb motors run a cooler stat than EFI/MPI motors. What is yours?

its carb

also how do i post pics

gen V and gen VI 454 engines use 160 thermostat

Registered members can't post pics unless you have an "offsite" account like Photobucket. I am a paying member here but use Photobucket because it's free and I belong to other sites that use V Bulletin that I use it to post pics to also.

Anyway...addressing 160* vs 140*...I think it's a non issue. If it bothers you switch to a 140* thermostat.

your on the money
