need advice on used outboard purchase...

bsteckel:

Motor as a ignition harness but no controls for throttle and shift, or trim/tilt and there is no prop either. I'd be willing to ship it but would rather have you come and hear it run first. If your going to spend the money I don't suspect it's that far of a drive for you (then again I have gone to Miami to pick up a boat before so I have no problem with driving!)

Older powerhead is just that (80's) mounted on a 1994 engine As THERM said MERC made a ton of these engines. When I got the motor the powerhead had two bad cylinders (oil reservoir hose came off at the injector and it didn't take long after for the problem to set in after that! - thus why the oil injection system is now removed.)

Instead of rebuilding the original powerhead, I purchased a older used 135 HP 2.0L powerhead off of Screamandfly.com. Suspect powerhead was rebuilt at sometime as the welch plug isn't stamp with a model number and typically they are. I rebuilt the carbs from the original powerhead and reinstalled them on the replacement ,bring it back to a 150. Believe the stator and trigger have been recently replaced as well based on their appearance alone.

i stumbled across a 1995 150 merc ... but it is a 2.5, not a 2.0

what are the pros/cons of the 2.5 vs 2.0?

comes with controls and stainless prop ... under 200 hrs asking price is $2000 .. compression is good at 125lbs in all holes. motor tested on ddt tester (not sure what that is) with no problems.

of course, this is what was told to me.

sounds like a good price

guy with the yamaha for sale seems to be very busy .. not sure why you would advertise something for sale and then never be available to sell it????

Since you say it was tested on a DDT, I'm assuming it's an EFI. If so it is one THIRSTY SOB, believe me I have one. They have torque that is out of this world though for a small V-6, but that 12-13 gallons per hour at cruise is a killer. Also a 25" shaft 2.5L EFI weighs in around 425 pounds. If I was considering a 2.5L, I would go with a 200HP for the reduced cruising RPM's. This will give you an idea of the fuel burn for a 2.5L 150, the older engines are close but slightly higher(about 5-8% more fuel burn).

how much more fuel does the 2.5 150 burn at cruise than the 2.0 150?

there must be some advantage for efi? less smoke? better response?

thanks

The EFI is easier to start, and runs a little smoother. Many say the carb motors are actually btter on fuel than the EFI, and they both use the same oil injection pump so oil consumption on oil injected models is the same. The EFI I have does have INCREDIBLE off idle performance compared to my 2.0L. I know my 2.5L 150 EFI burns 12-13 GPH on an 18' flats boat, I have a 2L 150 on a 17.6' bass boat that burns about 4-5 GPH at the same cruise speed and RPM's. The bass boat is lighter, but the 2.L is alot better IMO. The 2.0L will use a little more fuel at idle due to porting inside the engine, and the 2.5L has ALOT more torque.

[bsteckel]

wow, that is almost double the fuel consumption ... is there that much difference in weight between the 2 boats ?..

that 2.5 is 35 lbs heavier approx than the yamaha i am looking at .. and 40 lbs heavier than the 2.0 150 .. not a huge difference.but coming with controls and a ss prop, that is less things that i have to buy. unless the ss prop that came with my sea drive would fit, then the controls is the only difference.

but double the fuel consumption ... wow.

The bass boat weighs in at 800 pounds hull weight, my flats boat weighs in at 1400 pounds hull weight. They both run almost the same numbers at each RPM point, but the bass boat uses alot less fuel. It only has a 14 gallon tank in it, and I took it out one day for 2 1/2 hours and only burned 11 gallons running it the whole time on a river.
