wrxhoon1 Posted March 31, 2020 Share Posted March 31, 2020 I have a 2013 ,250 hp 4.2 lt Yamaha digital control with just under 300 hrs I was considering changing to go to 300. This is the lightest 250 4 stroke you can buy at 250 kg for extra long shaft and you only need 91 octane. How much are you prepared to pay? 1 Link to comment Share on other sites More sharing options...

Shearwater Posted April 27, 2020 Author Share Posted April 27, 2020 After a lot of looking around and getting the run around from a few would be sellers I thought I would let you know what I have decided to do regarding engines - I'm purchasing a 250hp Optimax - I was going to go with a Verado but it required so much change to my current setup it became a no brainer to go Optimax. So, there we are, so, within a couple of weeks all should be good to go and hope to enjoy the Opti for a fair while from now!

This will change the boat so much it will be like a new boat again, the extra 100hp will be a godsend when you need the power to get the hell out of dodge. Love to read how much of a difference it makes in your opinion having driven the same boat with both motors.

Shearwater Posted June 3, 2020 Author Share Posted June 3, 2020 Well, the Opti 250hp has been installed and I have had one decent run in the Coorong to get used to it. Certainly gets on the plane a lot quicker and the noise is less than the old Yammie 150hp. Currently it's running a 15x15 prop and is getting just over the 6000 rev mark - so I am trialing a 15x17 next week that will drop it down a bit - overall, I am pleased with the performance. When I bought this vessel there were 5 different floor levels - with various fresh water and fuel tanks etc - So, I have just finished changing all that and now have one level that really is terrific! Now I just need to learn how to set the Smart Gauges to how I want them ! 2 Link to comment Share on other sites More sharing options...
Shearwater Posted June 21, 2020 Author Share Posted June 21, 2020 The 14.5 x 17 prop was spot on with 6000 revs just reached - so all good to go, cheers 2 Link to comment Share on other sites More sharing options...
