Yanmar Kanzaki transmission slow to engage

We have a Yanmar 4jh4hte engine with Kanzaki Km4a2 marine drive. When cold, it takes about 5 to 10 minutes for the transmission to engage in forward gear. Reverse gear always engages immediately. In forward, the shaft turns but slowly no matter the throttle position. Once it engages in forward, it's good for the rest of the day. Any thoughts on the problem and resolution? Fluid level is OK. Use SAE 20 or 30 HD oil per manual. This problem was intermittent and is now frequent over this summer.

I suspect the forward clutch is going.
