looking at a 25'mako with 2000 yam 130's. I havent viewed the boat personally yet. I am wondering if the carb yamaha were worth getting or should I wait until I find one with SS or HPDI motors. The pics show regular yamaha covers with V4 130 on rear of cover so I assume that means it has carbs. The guy lists that it has 30 hrs on new motors. Any opinions? Thanks<br />also- will motor cowl covers list if they are counterrotating O/B pair or will I have to get model numbers to find out if one is counterrotating?? thanks

Re: 2000 yamaha 130

How good are the pics, if you have a good shot of the outboards you should be able to look at the props and see if they are counterrotating or not. Yamaha's are good motors as far as carb or wait for somthing else that is a personal opinion some people like to work on and set up carb motors others like EFI.

Here is best pic I have. Help appreciated Rad and others... usually the starboard engine would be counterrotating correct??

Re: 2000 yamaha 130

I always assumed it was starboard too. But the starboard outboard pictured isn't counter rotating. ?<br /><br />The Yamaha 130's are excellent. Yes they will have carbs. Same outboard as their trusty 115 carbed, but run 500 rpm higher and a bit more compression. Good fuel economy (for a carbed 2-stroke) and light weight for a 130 hp (358 lbs). They look well taken care of. I see no reason to go DFI over these motors.<br /><br />I've had a '84 Yamaha 115 carbed and a 91 115 carbed. Never had a problem with either. :D

Yep.. i figure they must be non-counterrotating pair. Does anyone know if there would likely be a steering/veering off course problem with these two on a 25' mako. Would anything altered/added be able to compensate if there is a problem with both being standard screw direction?

Re: 2000 yamaha 130

You could ask the seller or previous owner, maybe take her for a test run. Also a lot would depend on the steering system (hydraulic vs. cable). Twin 130's is a lot of torque-steer on a 25' er, but just the fact they are not CR's doesn't mean the end of the world. That Mako is a pretty decent boat, especially at higher speeds. I'm sure they knew they were not CR's when they put them on. :)

I run a heavy 23' Wellcraft with 2 OMC 1.6L Sea Drives with both props spining the same way and hydralic steering. No problem at all.

Re: 2000 yamaha 130

Boat does have hydraulic steering. Just concerned about drift from both props turning same direction. I have never owned twin engines before. I tested an aquasport 25 with twin 112's OMC and it had a bad drift that had to be corrected with large correction with trim tabs. That is reason I am concerned. Thanks for the info guys.

Re: 2000 yamaha 130

The port engine is suppose to the counter-rotating engine. The engines should be turning outboard so the starboard engine would be turning clockwise and the port counterclockwise. The 130's in that year shows a left hand engine available. Usually it has a label on the cowling, which neither of these shows. I would be concerned with them producing enough power to run this boat properly. I use to have a 89 25 ft Mako with a single 225 OMC. It ran OK but sure wasn't a speed demon with a load.

Re: 2000 yamaha 130

Thanks. I guess I will have to go down there and test it to check its performance. I would have thought it would be powered plenty. What should the range for RPM max be at WOT for these motors? Capt. Ken, What would you like to see as a good cruising on plane RPm and speed if you were setting it up with O/B's? Thanks (boat is 1980 25'mako CC)

Re: 2000 yamaha 130

The engines should be propped so that they turn between 5-6000 rpms at full throttle. I expect it will take somewhere in the high 3000 to mid 4000 rpms to keep this tank on a plane. That age Mako is a heavy booger. If it ran out any faster than mid 20's I would be surprised. My 89 Mako would only hit 24 mph a WOT.

Re: 2000 yamaha 130

after your last reply, Ken, I think I will just pass on this one.. Almost assuredly won;t perform like I want it to. oh well, old boat-new motors doesn;t always make a good deal. althought that is my favorite. ;) Rather have it that way then the opposite.

Re: 2000 yamaha 130

Found a couple older Mako 25's for sale that would indicate the twin 130's might be more than adequate.......<br /><br />1979 25' Mako CC with twin 150's claims 40 kts max and 33 kts cruise (about 200 lbs heavier). Also found a 78 Mako 25 CC with single 200 hp and another with single 235 hp for sale.<br /><br />Hope this helps.

Re: 2000 yamaha 130

Beaux - I don't know what Cap'n Ken was running but I have a very heavy 1988 23' Wellcraft CC with twin 1.6L V4 OMC Sea Drives (they never rated the hp for the Sea Drives but I figgure 120s). With four aboard & about 60 gal of fuel I get 32-34 mph @ 4400 rpm - GPS - ss props - salt water - Florida Keys - early summer.

Re: 2000 yamaha 130

Hull design really figures into the power needed to plane. Everyone knows that the flatter the hull, the easier it is to plane, but the rougher it will ride in a sea. The Mako is a full deep V. That's what gives it a good dry ride in rough water. Down side is that it takes more power to keep it up and running. Also, Mako put a lot of fiberglass in those hulls back then. Also noticed in the picture that the boat has trim tabs. Usually a sign there was a planing problem at one time or another. Don't get me wrong, my Mako ran out good. I just wasn't going to win any races. Dang that thing would drink fuel. It always amazed me on how fast your friends could dissappear when you pulled up to the fuel dock.
