[Dino89]

Hi
i want to do an oil change on both my 2 stroke outboards, can anyone recommend what i require to this on the following motors
1/ yamaha 15hp 2stroke
2/ mariner 25hp 2 stroke

need to know what to order ,quantity ,pump and oil type suitable for both motors and the cheapest supplier if poss
thanks

Buy the Yamaha gear oil pump-it's better quality than the Quicksilver pump and it should come with an adapter that'll fit the Mariner if it's a Merc based engine (mine did).

I'd be surprised if a litre bottle of Quicksilver premium gear oil wouldn't do both-though it's worth grabbing extra as it doesn't go 'off' if unopened.

Doubt it goes off if it is opened. Gear oil doesn't have too much in the way of aromatics that are going to flash off. Cap the bottle and stick it on the shelf.
