Due to the differences in engine compartment designs, and accessories supplied by those manufactures, clearances may vary from boat to boat. The applications listed are to be used as a reference guide only. Make sure to double check all the measurements before ordering by using the checklist below. If you wish to increase or decrease the size of the filter, see Universal 3-Piece assemblies below. (K&N Marine Flame Arrestor 59-1195 shown in picture)
IMPORTANT: DID YOU CHECK THE FOLLOWING?
- Diameter clearance around the existing flame arrestor. Can the flame arrestor diameter be increased?
- Height restriction, due to hatch clearance or any other obstruction. Can the flame arrestor’s height be increased?
- Do any vent lines connected to existing flame arrestor. If there are vent lines attached, measure inside diameter of vent line and order appropriate vent hose kit below.
- For multiple carburetor application, check center to center measurements ensuring enough space for two flame arrestors.
- Check diameter of carburetor.
