I will agree with you to a point on support from tohatsu usa. They did try to work with me over the phone actually they went out of their way to help me. However once I took the engine to a service center they dropped the issue with me when the service center said it works fine. I'm sorry but that service center isn't competent. It's a shade tree dealership that somehow got to be a service center. I wish I could show you through my eyes the workshop and the conversations I had with the owner. You would understand why I say this if I could show you. Dealing with the people around this transaction has been a mixed bag..on the con side a dealership that would not return my calls or emails until forced to and an incompetent service center. on the plus side tohatsu usa phone support did "try" to be helpful. Also your dealership who wasn't even involved in this transaction has impressed me with your willingness to back the product and try to help. I will give credit where credit is due but I will also call a spade a spade.
In the end the engine in operation doesn't have the umph to turn the lowest pitch prop made for it at 5500 to 6000 engine rpm which is where it develops it rated hp. Point blank.
Pre purchase. I did talk with the salesman about the application I was putting it to and what engine I was then using that It was going to replace with it.
One of the biggest irritations with the whole support thing was the total non response by the dealer up till the point I filed a credit card dispute.
I have at this point lost the credit card dispute and I do still have the engine. Since I can't afford to purchase another one I will just have to live with this one. It doesn't give me the extra power I had hoped to get by buying an engine 50% more powerful than my last one. It actually performs just under the old one.
I don't doubt that that shaft turning at 5500 to 6000 engine rpms will produce 6hp. As I guess the government certifies? However my engine and the other engine I have tested could not turn the stock 8 or 6 pitch props with enough power to get even close to that rpm. Maybe those two engines weren't personally certified by the government.
I have fought this thing out as far as I can. In dealing with the whole credit card dispute, I have found being the little guy sucks
but thats about par for the course for this whole thing. I'm not willing nor have the resources to pursue it further so I'm going in to in this situation now focus on the future and give what has gone before a rest.
As we have spoken of before I will be ordering one of the Special High Thrust props you sell sometime this spring when money is a bit better and I am able to get my boat back in the water. I will run all my tests again with that prop and report results and on the water performance to contrast it with the stock 8 pitch and the stock 6 pitch that have been tested already. As I am very interested in seeing what kind of difference we will see. We have a local prop shop here that I'm also thinking about talking to about a custom prop. maybe a slightly bigger 5.5 or 5 pitch prop... I think I will try and take the prop off the old engine in also and get them to tell me what the pitch and size are compared to the 8 and 6 from tohatsu. Actually I can probable take a ruler and figure that out myself.
maybe something to play with soon.
I am also going to try and borrow a dingy and run the on the water tests with the engine on it to see exactly how it performs with a super light boat with each of the props. I also plan on doing a pull test of my boat with another boat and the inline scale to give me solid numbers on a hull speed vs (friction resistance) curve for my hull.
i do bitch about things I think should be bitched about but I don't do it based on "I feel" I do it based on here are some concrete numbers. Every step of the way I have used modern technology to test and measure what I have reported in a scientific manner. Hopefully by this summer I will have the next set of numbers ready to be published. Maybe with the high thrust prop we will get some pleasant numbers. I hope so.
