      February 7, 2018 at 7:25 am Any suggestions on cleaners or paractices to de-grease prior to paint touch up? Motors are in “good” shape but want to get some fresh paint on them as we service this winter.

Has been great, about 20 hrs so far and love them. Port motor has generally taken a second or two longer to fire that Starboard. Today was our first cold day I stated the boat which had been sitting about 3. Port motor had trouble starting, cranked for 7-10 seconds. I stopped, advanced the th…

      January 27, 2018 at 12:43 pm If you hook it up manual, consider a old fashioned 5 minute twist timer at the dash.. That way you cannot forget..

      October 29, 2017 at 10:20 am In Tony’s post about the raw water pump and removal / service nightmare there is mention of “upgrading to a better pump” where the removal and servicing is not so tedious…. Anyone know what pumps are easier to remove and service? Attached is the mess that is on my port motor with a leaking raw water pump with signs of prolonged leaking…. Second photo is starboard motor’s pump and fuel cooler set up. Fuel h…
