Update on the OFS4 prop (15p) that I installed. I did love how much extra grip the 4 blade gave my Yamaha F200 and it’s handling in choppy seas and following seas. I knew I would lose a considerable amount of top end, but my top speed went from 45 knots to 30 knots and my WOT RPM went out of the factory range of 5,000-6,000 RPM as it would only reach 4,800. I like being on the lower end of that range for the type of boating/ conditions I’m in, but I think I’m a little over propped.
I worked with Ken at Propgods and he recommended the same prop (since I like the feel) but in a 13p rather than 15p.
I’ll report back with the new prop, I may keep the current one as a backup. My goal is to keep most of the 4 blade feel, but get back into my RPM range. I’ll be shooting for 5,300-5,500.
It took me awhile to give in to this advice, as I was liking how the boat handled when I fished. I had a ton of "grip" in following seas, got on plane soo much sooner (and stayed on plane), at a heavy sacrifice of top end speed. My friend noticed that the prop didn't "feel" smooth and doing more research has led to me believe that even with the extra grip I am still way over propped.Thanks for the update. I'm not up on the RPM specs on the F200 but I would think it may be the same as the bigger motors @ 6000, top end. I'd be shooting for the higher 5K's like 5700-5900 if possible. Don't want to leave anything on the table that could be usable, RPM/HP wise.
I have a lay down soft vinyl removable flooring that gave them some cushion. They had a good amount of blankets and sleeping bags and actually set up their small tent in the cockpit in case it rained.How did the two sleeping on deck fare? I hope they had self inflating mattresses or something.
