I think I am going to buy a new boat with 525efi's..... anyone have an idea of the life expectancy or how many hours they are running before top end refreshing?? tired of going down the road
with blowers and rebuilds

thx

If you're not too hard on them, 400 hours before top ends

I was told its about the same at the 500efi's witch is between 300 and 400 hours.

.

what is the cost to have MercuryRacing do the complete refresh on the 525 EFI's ?

Trick question.........Many new 525's have been torn down with relatively low hours when the sh!tty headers leak!

Usually a complete rebuild from Merc is 12,000 - 14,000

I have / had over 450 hours on mine.... they are currently at Potter Performance getting rebuilt

Tooooo Many!!!

I was told around $12,000 as well.

How much at potter?

A good engine build is usually about 8,000- 9,000

U rebuild 525s after the headers let go and ruin em

100hrs
200?

20?

Ticking time bomb
