NOA, NOAA any info

I was told that this organization at one time allowed for a 90 yamaha to be raced against the SST60 engines. I would love to see a picture of one. Thanks.

The SST60 was not in existence when NOA raced. The 90 Yamaha raced against the modified OMC's of the day. The 90 powerhead was mounted on a 2 cylinder 60 Mariner short housing. It was the same bolt pattern. I had just built a 4 cylinder 85 Merc with 4 carbs that was very competitive with the Yamaha. The organization folded before I got the bugs worked out. James Blake had the 90 Yamaha. I helped him assemble it after Jr Eaves did the machine work. It made the other motors pretty much compete for 2nd place.

That is the same story that I was told 5 days ago. How do I get in touch with James Blake. Does he live in Soddy Daisy, TN.

I was there when this went on. Allowing the 90 Yamaha powerhead to run on the smaller leg and lower was a very bad decision. The old NOA rules stated that the engine had to be "stock appearing". Stock appearing to who?? Put a dollar amount on the machining that had to be done and there is the reason not to allow it.

A friend of mine has what i think was the last one running. This one was on a V bottom. I thought i could get a pic. of it but called just now, an he no longer has it. Blake may have a pic. of his but he no longer has it. Sam was right about The OMC's running for second place but remember they were 49 cu. an the Yamaha was 69 cu. an both were Looper's wonder why they did not run the 70 Yamaha that was i think was 49 cu. I guess we know that. The class in NOA was 40 to 70 cu. so it could run but should not have been on the Mariner lower unit. This was one of the worse things that happen to NOA, it killed a class that had a full field of boat's. get the feeling I didn't like the Yamaha even if Blake an I were on the same Team. The first time one showed up on a V bottom, a very out spoken owner Roger Prosser said at the drivers meeting they have already killed the Tunnel class, now they are trying to kill the V bottom.

I do agree with all said, that was before my time, didn't seem fair. My only interest is to speak to those who built the 90 Yammies. I want to built one that will make good power. I have one built off of the 60 Mariner and just picked up a mint 60 mariner for a secound build. It was not a bad job at all. On the first I am running the bigger 90 case, on the next I will use the smaller 60 case. Thanks for any help. And I would love to see a 90 on a tunnel.

There were a couple that ran well with the big case but ran Merc props that were very high $ some around $1000.00 back then. with low water pick up an nose cone. The Mariner unit had to have the same thing. JR Eaves put finger ports an other mods in them. I think he was around Soddy Tn, Sam may know for sure. If you can fine Glen Renoles (sp) a drag racer from around Kinston Tn he may be of some help, a guy in Kingston named Oran had one of the faster ones, Glen would know if he is still around. but Eaves did the motor work. we build a couple but that was a long time ago. Good luck with this i will try to get a pic. from Blake for you. My other post was just to tell the racing History of this motor.

NOA allowed the larger displacement 90 Yamaha to be raced against the OMC 75 (40-70 c.i. class) in 1985, and that killed the class.

I would agree that without restrictions that, that was not fair by anyones standards. And also there was a class developed where the 90 ran against inlines and V4s and was quite competitive, then the rules allowed for some wild mods and from that piont on the V4s were unstopable and that killed a class. Rules are there for a reason. Here at home we just go play, it always turns into a race of some sort. Me haveing the smallest engine is a plus. If I get beat by a 2.5 or 2.4 or even a 2.6 No one can go brag, "yea I spanked that 90 with my 2.5" just doesn't get applause. I have never been at the back of the pack with my 90, acually closer to the front is most common. And the fellas that wind up behind me catch hell from thier buddies, Not me. I just enjoy going on the run.
The biggest reason for starting this tread was to find the folks that have 90 parts that make one run, or the knowledge to do so. I have been directed to some knowledgable folks and have a few great conversations about the 90. It is a stong motor, and I will eventually get mine to make RPM, 7000 is not enough. I want more.

This the start of the 40-70 V class.
