Hi all. Just found this forum and will now proceed to ask two questions that have probably been asked 10,000 times before. Be kind to the new guy please. First what year is my 9.9 B2 355A-1 62005. And what needs to be done to convert it to 15 HP? I just got this motor and it hasn't been run for years so I'm guessing I'll have to rebuild the carb anyway so might as well dial up the HP if possible. Thanks for any insight into this motor.

Somewhere between 1988 and 1992. All you need is the timing cam to boost it up to a 15. It's available from any Nissan or Tohatsu dealer

Once more if I may. Do you have a source or part number to buy a timing cam online, I can't find it listed anywhere. Thanks again.

I think we are the only ones who list it online, but the part number is:

Re: 9.9 to 15

if that is the only difference, then what was the cost difference of the two motors when new?? if it was more than about maybe $2-00 then the company is ripping off consumers, as surely the difference in manufacturing one motor with X cam and one with Y cam must be minute!! and as such they should be reported to the relevant authorities for deception! especially anyone who purchased a 9.9HP

Re: 9.9 to 15

What something costs is irrelevant to what something sells for in a capitalist economy. Demand determines price unless there is regulatory interference. Using this engine size range as an example...15 hp engines sell for $2000.00. 9.9 engines sell for $1800.00. The manufacturer could spend the time and money to purpose build two completely different outboards. That would cost them X for the 15 and Y for the 9.9. Or they could save the development and manufacturing costs by simply detuning one engine size down to another. Basically they save the cost of Y. Since they have spent less it saves them money. The manufacturer looks at other brands that sell a 9.9 and 15 and prices at MARKET value. IE They join the pack to some degree. There isn't any deception involved. The consumer is getting what they pay for....It's just the manufacturer is enjoying a higher profit margin on the higher hp. Say they make 30% on the 15 and 20% on the 9.9. They average the profitability that way acoss the line to get the profit margin that they need/want.

Austraila is a little further along the socialist road than we are( we are catching up though) and I can see why you would rasie your eyebrows...But, profit is the motive for a company to exist. It's not about being fair, it's about stockholder equity. Now in the long term it actually does benefit the consumer to some degree because the more money a company makes as profit, the more money a company pays in taxes. At least thats the theory.

Re: 9.9 to 15

You assume the company is ripping off the consumer by selling the 15hp at a higher price than the 9.9. But if you consider that maybe the company normally gets X% for a 15hp but since they detuned it now they only get Y% for the motor, then they are losing profit by selling it as a 9.9hp.

In other words if it costs $2000 to make a 15hp and they normally sell it for $2300, but when they sell it as a 9.9 they can only sell it $2100, whose getting the short end now? It costs the same to produce that engine but they make less money. So unless the consumer is willing to pay the same price for a 9.9hp that they do for a 15hp, then it's the company that's losing on this deal, not the consumer. :love:
