Steve,
I liked the extra's you did to yours...
what is the two strainers and 3way valve about on the suction? Where was the second suction going, to the bilge or was it to recirc something with your cold weather?
Tower todd- if the filter is mounted sideways(not the best engineering feat) and the oil pan is a foot below the filter with no check valve thee oil can leak back into the motor and out of the filter- due to gravity....the same vovlo mechanic or "salesman" in the same sentence as recomending vovlo oil filters did recommend using aftermarket secondary fuel filters to save a few bucks. I have good luck w the motors, steve in ak- did you replace the motor w another 200 hp motor and did that help? or did you increase the horsepower to get more"balls" maybe the lack of balls was due to the small duo props on the outddrive? Just trying to help a guy out...definetly not trying to hype vovlo motors......I would recommend the 41p to the guy looking at the boat and if he needs more power just say fuck it and order a 42 wesmac with a 1000 hp caterpiller aand he should be good to go
