Problem fixed: Shift lever seals and impeller needed replacement

Best tip I received from another site was to use a ratchet strop to hold bottom leg as I eased it off the engine and also when I had to reposition it with exhaust, water drive shaft and shift.

Items were shipped promptly if in stock. Reasonable prices.

Although the site said all parts were in stock and would be shipped immediately, it was over 3 weeks before I received them. Parts were fine once received.

Problem fixed: Motor was overheating

This is an easy repair. The thermostats are located above the cylinder head and are easily removed by unscrewing the caps.

Problem fixed: Fuel coming from fuel pump, motor not been used for 5 years so it needed a major service.

We originally found your site as we wanted to replace the tilt assist cylinder. We later found a local to re-gas & service the cylinder as they are only a strut it is now working great! Replaced fuel/oil pump, serviced carbi's, changed leg oil and replaced water pump. We now know we have a very reliable motor. Crowley Marine made it doable due to fantastic prices. Thanks
