What year is my Yahama Mariner 25hp and do I need an impeller for it?

[jooleyen]

Hi, I've got a Yamaha/Mariner 25hp motor. I think it needs an impeller as water is not spitting out when it's running.

Can anyone help me find the part and where I can order it?

The tag on the motor reads - Mariner 25M 695 L 315306 Made in Japan. I'm not sure what year it is.

Thanks

Even if you find that you don't believe you needed a new water pump impeller once torn down, it's one of the most important parts of the cooling system as to where it's just already time for new impeller anytime you suspect a cooling issue...Or lot's of time has past.

The impeller part number alone is 84797M as noted as item number 18, http://www.iboats.com/Gearhousing-As...iew_id.1696219
