I am also in Denmark and have Scorpion engines that require 98 RON (91-92 PON). Boat is kept in the water so I have the same problem. There are very few gas stations on land that have the high octane fuel here because of the MTBE content, but I am lucky that there is one gas station in my town that has the high octane fuel and it is on my way to the boat :) so I also use cans to carry the fuel and really it is no problem. If I go for a longer trip and need to refuel at a marina to be able to return home I carry an octane booster.

You can buy products like this: http://www.tank-depot.com/product.aspx?id=139 that makes it easier.

You are correct. My error.Thanks

I know some 600 users using this poduct with success with the 600 `s

After lots of posts on different sites and lots of emails from folks I trust,general consensus seems to be that 600's not run hard will be fine on 89 with Kemco boost as added insurance. But telling the buyer that troubles me,I don't want to cause him a problem. Am considering having him log on to OSO,check this thread,and let him make the call.I would rather lose the sale than mislead him.Your thoughts?

Problem is If you tell him its ok you will marry that boat and every problem will be because of that.I personally think it would be fine with some octane boost.Or filing up halfway with cans of 93,(1/2 89 1/2 93) will be cheaper to but it has to be his call.Put him into the 353 its a big 35 and he will probably be very happy.Won't a 353 with 525s be faster than a 382 with 600s anyway? Good luck

This may be the toughest sale I have been involved in in 42 years as a dealer.Customer is a great guy,we have become friends since he bought a 353/496 boat from me last year.353/525 and 382/600 are about the same speed.+/- a little. But he is not into speed,he likes the big boat feel,and the genset,doubt he will run over 65mph more than a few minutes in a season.Obviously,for warranty and liability purposes,Merc Racing goes by the book,as do I.I'm sure he will be fine with 89 and 93 when he can find it,and octane booster when he can't. But I was clear in explaining that my thoughts will be overridden by Merc if a fuel related failure occurs.He is going to make a decision Monday,382 or 353,and my driver will leave Tues with one. I have done all I can,covered all bases,and offered to walk away completely,and he will still have his 04 353,but he said no,he wants a new boat next week. It will be his call completely.Sometimes I miss the old days when the only decision a buyer had to make was did he want a 65 hp Merc or an 80 hp Merc on his 15' Glastron,it was a big price difference of $400

Can you just order a 383 with the options that would make it work better for him? Or swap that boat with another dealer.....

Robert,
pull the 600's out of the boat and trade formula for some 525's they have. Hopefully they have aboat they can put the 600's in.

The best part is it sounds like you and the customer have a great relationship. Good luck to both of you with his decision. My guess is he will be fine with the boost considering how he runs. I always ran 93 in mine and never had a problem.

Hope it turns out well....:D
