"I lost my first motor to exha
"I lost my first motor to exhaust manifolds failing. I repowered in 2001 with my 4.3l 190hp.
I had to replace my starter after the second season and in removing the exhaust to better access, I noticed the starboard side manifold begining to fail. I replaced both manifolds.
My question (since I am now 2 seasons on the replaced manifolds) - should I change every two seasons based on the original manifolds? What is a good life expectancy for manifolds on this engine with average to moderate use each season in salt water.
I just ordered a new set of manifolds and now wonder if I should try to stretch another season out of the ones on the boat (would be the third season). Any way to test other than to visually inspect for rust indications on the engine exhaust portion of the inside of the manifolds?
Manifolds, elbows, risers, etc. are expensive, but far short of what it cost to replace the motor.
Appreciate any thoughts or ideas!
