Yamaha V6 Fuel Pump Kit by JERRY - RANDLEMAN, North CarolinaJune 08, 2010
Ryan at iboats said the third kit was on B/O. He called to get shipping status while I was on the phone. He said they would ship on the 4th of June. On the 4th I received an email stating items had shipped. I asked for priority mail shipping. The package arrived the next day. The parts fit perfectly! Excellent job by Ryan and iboats. Thanks

Yamaha Fuel Pump rebuild Kit by David - Lewisport, KentuckyJuly 07, 2012
Kit came just as shown. After disassemble of factory fuel pumps I noticed that the thickness and material was different. The factory diaphrams were thicker and made out of thougher looking/feeling material. These will work I'm sure but, if I ever need to change them again. I will buy complete Yamaha pumps. Yes the pumps are more $$$ but what is a powerhead worth?

Just what I wanted by Sandra - Hillsboro, West VirginiaAugust 05, 2011
I received and inspected the gasket set and it was as advertised. Once installed it worked perfectly and I was able to get back on the water quickly. Will use Mallory products again if I need marine parts.
