Well I just did the four plugs on the right side of the engine, rechecked gap which they were all fine there, put them back in reseated the plug wires and It seems to have smoothed out. Think I'll still pick up a set of plug wires and replace them.Marine or Auto are basically the same, just different lengths. Most marine are longer because they go under the exhaust manifolds where autos go on top
Most times if the motor is missing and its not plugs or fuel its the flat cap (crap cap), there always going bad and look great
Based on a strong recommendation it would work I took a chance on the equivalent automotive set but as alldodge says, they were too short and had to buy the OEM marine set.Yeah be nice to know what the automotive equivalent is....
