I really like the NGK plugs in the autos and was not a big fan of Champion. I just have really great results with the basic NGK plugs. Our marine mechanic recommends champion for the GM marine setups and so we run those. He has many years of experience with these mercuisers so we go with his advice and he certainly has earned our respect. He keeps us running smoothly, gets stumped now and again but he will figure it out, no doubt there. We have good luck with the Champions in the GM mercruisers.

MR43T is definately the plug i would run. They are stainless threads and body and are designed for this engine.

1 heat range hotter than stock, extended electrode for a good solid burn. Get some good fuel or some octane treatment and set you timming a touch hot, maybe 10 degrees instead of 8. Hang on.
NGK makes a compatable plug. Look at the cross over chart.
