Oh Boy!!! I had aquired last year a 1996 Larson 174 17 ft bowrider equipped with a Volvo 3.0L 135hp I4 engine in excellent condition. One problem however continues to plauge me during my outings. While on plane at 4000rpm and after about an hour or so of operation the engine gradually loses power, sputters and quits. All other engine indications are normal (eng temp 150-160, oil press and voltage). After sitting for about an hour and a half (fishing while waiting) it will start with no problem. I noticed the fuel line running from the fuel pump to the carb (A Holley 2bbl) is metal and runs along the lower end of the block up around the head to the carb REAL close sometimes in contact with those components. Could I be suffering from fuel vapor lock? And is there a suitible substitute for the fuel line?
