Repowering C-Voyager

It has been a-while since I have been here or out on my boat. I am in Gooseneck Washington now & plan on doing a bit of fishing on the Columbia River in The Dalles Oregon area. As some of you know it is often windy plus strong currents in this area. The 50hp Honda works fine for most situations but with 3 people on board plus gear the boat is a little underpowered in these conditions.

Anybody know anything about the Honda BF60 and are there any other outboards out there in the 65 to 70hp range that are lightweight, under 250lbs?

The 40 and 50 Hondas are on the same block, 808 cc displacement. The 60 Honda, is 998 cc. The Yamaha 50, 60 and 70 are all on the same block--about 1000 cc. So the 60 Honda and the Yamahas are going to give your more torque = "pulling power).
 
I only can speak for the F70 but it impressed me for a couple of years on a past boat. A whole new class of power beyond the 50 you have now. Glad you are getting out on the river and keep enjoying Gooseneck. I haven't been through there for months but its hard to stay away from that region on the bike.

I don't know why there aren't more discussions/info on "hot rodding" outboard motors. I found several sites that discussed the difference between the Yamaha F50 and F60. Some said that the only difference was an air restrictor and a different ECU map. Others said that the ECU could correct for the removal of the air restrictor and that's all it took to go from 50 to 60. Don't know.

It's possible that OBs are tweaked more than most car engines and, therefore, there isn't much to be gained from fine tuning work on the head, valves, exhaust, etc. But it seems likely that, as with cars, there may have been production savings in some area that could be improved aftermarket. Same engine, same weight, additional 5hp. That sounds okay.

You could always add a nitrous oxide system to your OB. For an additional 10 lbs, you could almost double your horsepower. https://www.summitracing.com/parts/nos- ... gK74vD_BwE

You would also need to double your transom. Which brings to mind the CG tag on the CD 16. 55 hp is max.

The CD 16 is great for three people, as long as they each have their own.
 
Dave; You might need to be careful about this depending on how you use the boat. My insurance company said I cannot put a higher horsepower than rated motor on my boat, and have them honor accidents any more than they might not if I tow something well beyond the rated towing capacity of my truck or if you pile passengers in above the load capacity of my boat. C-Dorys are not high performance boats designed for large motors, at least the 16-22. Probably not a problem for just you and your family, but if you carry passengers, it could be. According to the C-dory site, the max HP for a CD16 is 55 hp. Happy boating!!!

Dave's "16" has been heavily modified and is 18' long. See this link for the thread about that. So bottom line, I'm doubt the factory capacity plates are relevant to his situation.

Dave - nice to see you back. The Tohatsu 60 horse 4-stroke weighs 262 lbs in the high thrust model and 243 lbs in the normal version. Those might be options.

By the same token, if he's told the insurance company that he has a 16' boat, but it is not, then maybe his insurance will decide that their coverage isn't relevant either.
 
Dave,
Great to see you back! I've missed your wisdom on many topics. Your boat will handle 75hp with no problem. I've seen your boat many times and know how you handle it, you use more common sense than most boaters.
Hope to see you on the water.
 
Thank you gentlemen for your input.

Greg - when your get down this way again stop for a visit. I am the only farm between Harms Rd & O'Brien Rd on the Centerville Hwy. During the summer I believe there is more motorcycle traffic here than cars.

Jason - I do like the Etecs. I had a 90 on my Marinaut but I felt it was a little underpowered with 4 people and full fuel. I think the 50 would be a little small for my 16 & the 90 would be too big. I still call it a 16 but it is really I8 feet.

Mark - I like your tag "The CD 16 is great for three people, as long as they each have their own". That is why I added two feet onto the "C-Voyager"

robhwa & ssobol - my insurance company has seen the thread Roger referred to & have no qualms about insuring my boat.

Brent - I don't know if I will have a 3 blade prop on a 4 blade. I suppose it will depend on the outboard I get.

Roger & Larry - thank both of you for the welcome back. I have missed both of you on this forum.

And last but not least Bob-thank you for your input. I have always valued your advice & look forward for more.

As you can see from Dave's response, he's a straight shooter with the insurance company (and from my personal experience in every other way). His boat is only listed in his profile as a 16' boat because there is no pulldown for a stretched 16 or 18' on the site.
 
Howdy Dave, and great to see you back on the site. It has been "a while". Looking for more spots with your tag line. For those not acquainted, here is C-Voyager.
