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 ## Frequently Bought Together - big-autoparts Water Pump Impeller 369-65021-1 47-16154-3 18-3098 for Mercury Sierra Tohatsu 2HP 2.5HP 3.5HP 4HP 5HP 6HP - Quicksilver 16248 In-line Fuel Filter for Mercury and Mariner 2-Cycle and 4-Stroke Outboards - NGK Spark Plug, NGK DCPR6E, ea, 1 --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.gr/products/385978005-water-pump-impeller-369-65021-1-47-16154-3-18](https://www.desertcart.gr/products/385978005-water-pump-impeller-369-65021-1-47-16154-3-18) --- *Product available on Desertcart Greece* *Store origin: GR* *Last updated: 2026-10-22*
