In one of the early reviews of the Optimax (don't remember which model) Powerboat Reports found the engine to be loud compared to competing products. Is this still the case? The engines I am looking to possibly buy would be the 135 Optimax if I downsize and buy a new boat, or possibly a 225 if I repower the old one (there is a reconditioned 2203 225 on iBoats for under $10K).
