## Questions & Answers

**Q: I need a impeller to fit 2015 colman 5hp**
A: It worked on a 2-horse Nissan and a 6-horse Tohatsu for me. Tohatsu made both engines. I don't know who manufactured the Colman.

**Q: will this fit a 1956 Johnson 7 1/2hp outboard motor ?**
A: Probably not, this fits smaller Mercury and Tohatsu engines......you need to get ghe serial number off your engine, go to Marine Engine site, plug in the number and it will give you the correct part number.

**Q: did this product come with the o ring?**
A: No.  Just the impeller.  It is a real Westerbeke part, good quality.  Lasts about 400 hours in Onan 11.5KW marine generator.  At 500 hours, need to go fishing for missing vanes in the heat exchanger.

**Q: Need help finding a 1978 evinrude 115 exhaust manifold gasket**
A: Try Sea Way marine
