Hello all--
I have a 2017 Yamaha F25LWTC and am preparing for a new water pump install. I will be installing a complete WP kit with new bolts. I asked questions in Yamaha forum but no answers yet. While I wait for some responses, I thought I'd inquire on my old stomping grounds here at Honda forum!!
my OEM Yamaha manual does not provide water pump bolt torque values. Not sure why. Called a Yamaha dealer and they could not answer this.
Also, the manual calls for Loctite 527 thread sealant to be used on WP bolts and many other bolts used on motor. Difficult to source this Loctite 572 and they want like $30 for a less than 2oz bottle!!!! Dealer didn't even know what 572 was....they thought it was thread locker...it is not...it is a thread sealant (see attached TDS).
NOTE: Over the years, after a wire brush cleaning, I use marine grease on bolt threads for most, if not all bolts on my marine engines.
Curious about comparable Honda motors.....
Does Honda OEM service manual provide guidance on sealant and torque values for these BF20-25hp models:
1. A thread sealant for water pump bolts?
2. Water pump bolts torque values?
Thanks!
