Non-Yanmar Filter - use caution
As posted here in the past, non-Yanmar filters may lead to futere problems. I inquired with Yanmar and they said this...Aftermarket (non-Yanmar) filters fit, but they lack a check valve within the filter that allows oil to drain back out of the filter and/or the engine. After repeated start-ups, oil must be recirculated thru the engine instead of just resting up there inside. Eventually, this leads to unnecessay wear on the engine.It may just be worth spending $4.00 more for that Yanmar filter in the long run.
