Want to upgrade my controls ???
 

So my 20sf currently has a 95 Merc VRi 150 efi i really want to upgrade the throttle control on it to a new more modern version. How can I find out or do any of you know which trottle control is compatable with my engine ?

Re: Want to upgrade my controls ???
 

IMHO, Yamaha makes the best controls out there. And they will work with that engine.

Re: Want to upgrade my controls ???
 

Really ? The Yamaha controls are compatable ? I did not know that all the binnacle gen 1 or 2 mumbojumbo confuses me.... Caymanboy I love ur boat its the reason I got a SeaCraft. mabey when I am ready you can do the floor and paint on mine

Re: Want to upgrade my controls ???
 

i have a merc one on my boat. i was going to buy a new one because this one looked horrible. i ended up on ebay with a new chrome cover for it and now its nice again. cheaper and easier.

Re: Want to upgrade my controls ???
 

Thank you! Hopefully you got a SeaCraft because of the ride! But they certainly have great classic lines.
You might have to change the cables, (go with the best) but I like the Yamaha 704 Premium control, you would still have the T/T switch in the handle which you could wire up to the Merc wires.

Deff went with SeaCraft because of the lines and the way it rides is a huge bonus, the look of urs gave me the inspiration I needed to pick up a boat of this age.......

So if I go with the Yam controls I just need to get the corresponding cable and splice in the T/T to the exsisting wiring correct ?


I really want to know if this one works though. I think it looks so clean

I looked up the Gen II shift cable he listed and found a pic of the cable ends. The end that connects to the engine looks like the right one for your '95 motor, but the end that connects to the remote control is different. I suspect you'll have to replace your shift and throttle cables to make it work.

That`s a good motah, but it has a gremlin. The oil pump gear is composite and they fail. Replace asap.

Decarb it and run good oil.

You would have to get 33C type cables and the Merc. adapter kit for the Yamaha control which is by far the best on the market.

Re: Want to upgrade my controls ???
 

My black Max is EFI and it is already converted to pre mix. I have ran 89 octain could I or should I run 93 ?

Will check into that. Any good sites to buy these parts from ?


Thanks for the info I am going to see which option is best

Re: Want to upgrade my controls ???
 

My OMC control is hands on all the time. Tough to modulate, even with teleflex xtreme cables. Much smoother and sweeter than a pop in the driveway though. Coulda been Jupiter inlet.

Turn right Irene,

If you're burning E-10, what you have to consider is that if you ever get enough water in the tank to combine with all the ethanol, so you'll lose up to 4 points of octane! :eek: That means your "89" octane fuel is really only 85 octane, so you'd be at risk for detonation (which you can't hear on a 2-stroke, since there are no valves to rattle), since that motor is probably designed for a minimum octane of 87! Detonation is the "pinging" you hear in your car if fuel is too low in octane, and is bad news for the motor, as it puts very high shock loads on the rings, pistons and bearings! However you'd be ok with losing 4 points from 93 octane fuel, ASSUMING it really has the advertised "LESS than 10% moonshine" in it!

This last assumption can be significant. I believe the ethanol is added at the distributor, so you're depending on a human that's not hung over or high on it, to add the right amount of gallons of moonshine to the tanker truck! After reading Fr. Frank's post on ethanol-related problems on his motor, I got one of these ethanol testers and check the ethanol content of the gas every time I refuel. Fr. Frank's mechanic said that even if you use a fuel preservative like Stabil or Startron, THEY DON'T WORK if ethanol level is over about 7%! I've never found more than about 6% at the stations I normally use, but given the cost of potential repairs, I figure the cost of the tester is a good investment!

One other tip . . . water in the fuel is also bad news for fuel injectors, so make sure you have a good filter like a Racor with the plastic bowl with drain so you can check to see if you're getting water in the fuel! BRP has added a water separating filter and water sensor on the newer E-TEC's and I'm thinking about adding one of those kits to mine. I believe other engine makers have done the same to theirs also.

Buying non-ethanol gas from a marina is no guarantee it won't have water in it! On my 700 mile circumnavigation trip last year, I burned non-ethanol gas the whole trip, but I checked the filter every time I refueled. I found water after refueling at Clewiston, St. James City, Gasparilla Marina, Sanibel, and Chokoloskee! From Flamingo on and back up the east coast, I found no more water.
