Check those fuel and cooling lines....

[Wally Boggus]

I did an oil change last weekend and after spending some time in the engine compartment I noticed some undesirable chafing on a fuel line caused by vibration against the rear edge of engine compartment bulkhead on the starboard side. Another chafing problem was noticed due to contact between one of the heat exchange hoses and the drive shaft flywheel. If this had gone unnoticed the mess would have been worse than the one I made removing the oil filter with a screwdriver. You might want to inspect your lines as well. I can't remember the old saying about an once of something is worth a pound of something else, but it works for me.wS/VCopa Cabana

Typical of Hunter

The chafe problem is but one example, unfortunately typical of Hunter's poor quality control and frequent inconsistency in their manufacturing process. My '99 340 had fuel lines resting on several sharp places on the engine block...badly chafed hoses discovered when I changed filters. On a friend's 340 (a few hull numbers away)some lines were ok, some were not.

bad routing

310/320 owners beware! On reading Wally's article I ran my hand down fuel lines. Both nearly through on a 11 month old boat after rubbing on plywood at rear of engine compartment. The movement of a 2 cylinder on tickover is something Hunter obviously havent allowed for. Many thanks Wally-saved me a LOAD of trouble.
