well i a 60hp evinrude I'm not sure of the year if that makes a diff,but I'm sure there is a diff from car plugs but don't know the best place to get boat motor plugs from and i did some research on here and found Resistor Plug and a standard plug and there's a 30$$ diff between the two so ware is the best place at the best price??and what is the diff between the two kind of plugs?

From the NGK website....

Q: When should I use a resistor spark plug?

A: NGK "R" or resistor spark plugs use a 5k ohm ceramic resistor in the spark plug to suppress ignition noise generated during sparking.

NGK strongly recommends using resistor spark plugs in any vehicle that uses on-board computer systems to monitor or control engine performance. This is because resistor spark plugs reduce electromagnetic interference with on-board electronics.

They are also recommended on any vehicle that has other on-board electronic systems such as engine-management computers, two-way radios, GPS systems, depth finders or whenever recommended by the manufacturer.

In fact, using a non-resistor plug in certain applications can actually cause the engine to suffer undesirable side effects such as an erratic idle, high-rpm misfire, engine run-on, power drop off at certain rpm levels and abnormal combustion.

Get the motor serial number and contact Evinrude directly. They can give you guidance on the correct plug and gap. You don't need "resistor" plugs on that motor.
