Q:
I'm looking for a impeller kit mercury marine?
A:
You may view the impeller kits we have available on our site here: http://www.iboats.com/Mercury-Impeller-Repair-Kits/dm/--view_id.271497 You will just need to identify your engine by the cross-referencing chart. If your engine does not pull up, unfortunately we don't carry the kit for your application.


Q:
Will this fit a 1978 75 Hp mariner?
A:
We determine fit by the serial or model number of the engine. We do not have enough information on this engine to determine if this will fit.
