all honesty needed! mercury(yamaha) 90hp 4 stroke performance

Kracker Jack said:
I have researched these motors for the past 2 days. And i hear nothing but great things about the smaller block 150's. As was stated the bigger blocks had the issues. The guy is having the entire fuel system gone thru and all fuel and vst filters replace and injectors done and new water pump. It is a 25" shaft so i will be building my transom up for now. And doung a solid transom probally after the fall. Motor comes with all gauges,harneses,oil tank and controls for 3500.00. Its a 2004 with 390 hours on it.

For 1500 it's a good price. Just run some clean oil. That 2m is very dirty and will cause carbon build up on a DI engine.

For $3500(I think the $1500 was a different engine) it's a good price, but personnally I would pass. When they're running, they run great. BUT just one repair can turn one into a parts motor in a hurry. With DFI engines what would normally be a simple repair can cost as much as another engine of the same vintage would. Then figure in maintence costs along with the need for a dealer to do electrical repairs, they can get pretty pricey. I considered a DFI when I had my HYDRA-SPORTS for the fuel savings, until I figured 1 or 2 dealer repairs in. Then all of the sudden my old carbed thirsty 2 smoke sounded pretty dang good. Yep I used 20-30% more fuel than a DFI would have, but I could do any repair it needed, and parts were easy and cheap to come by.
 
Well its official!!! Im not going with the 150 hpdi or the mercury 4 stroke 90.

Check it for corrosion CLOSELY! Suzuki's are KNOWN for corrosion issues. I love SUZUKI outboards, but I also know you have to watch for corrosion with them. I know Rm likes his JOHNZUKI on his V-20.
 
Yeah, my buddies Suzuki 140 has corroded badly. Just broke two bolts holding the water pump housing, and two holding the foot. Not to mention the corrosion all over the power head.
 






Guys a mechanic in the coastguard. Well taken care of 6 years of its life was spent on smith mountain lake (fresh water) here in virginia. Im intrested to see wht she looks like up close. He has run in brackish water.....still has salt in it but not as bad as true ocean water.

Look VERY closely at the lower unit ESPESCIALLY where the prop goes into the gear case. Suzuki's are NOTORIOUS for corroding in the gear case area and splitting where the propshaft support goes in.
 
I always knew the 2 strokes had this gear case issue...but didnt know the 4 strokes did. The only problem i heard from a guy who is the local suzuki guy said a plug in the mid section is where most of the corrosion stemed from on these 4 stroke. I have seen some frakenstien welding done on a 2 stroke lower!!!!
 
search my posts for DF140 for details.

I have a 2004 and I love it...but... it did have a known problem with corrosion in the exhaust channel where a steel plug is. The replacement "Engine Holder" part does not have the plug, it is solid aluminum.
That cost me $1800 incl labor.

Recently I replaced all internal engine block anodes. They were due but the block looks fine. You should buy replacements and o-rings before removing the anode covers

I replaced the Idle Air Control Valve last year, causing stalling when backing off throttle fast. The codes of flashing lights on the Multigauge pointed me right to the problem.
Boats.net has all parts and diagrams. I have a pdf of the service manual. pm me.

It is a great motor for the money. It will push your v20 to the mid 30's at wot. 3.5 mpg on 120+ mile round trips at 30 mph.
Turn the key after 6 months in a snow covered field- it starts. Love it.

I dont remember which one of you is from camden county, NC? Ncgarage? Bluerunner? But the motor is on billets bridge road not to far from one of yall.
 
Well its official. I own a 140 hp suzuki. So i looked at all corrosion spots nothing to write home about the motor was really really clean. I did the hour meter trick with the analog tach gauge by turning the key on but not starting and the needle on the tach will rise to the rpm that shows the hours on the motor for 3 seconds. Meaning if the gauge rises to 3000 rpm the motor has plus or minus 300 hours on it. Well the needle on this motor went to 2500 rpm.....i almost **** my pants so i did it 3 more times and the same thing...2500 rpms so i called my suzuki tech and said this cant be right! 250 hours! On a 2002. He said the hours from the gauge were always rightand corresponded to his computer. He then said congratulations you have officially hit the motor lottery and have found a cream puff! He then said buy it!!! Buy it Immediately!!! Im so stoked right now!!
 
on the 2004 you gotta count the rev limit light flash because it starts over after 5000
so 1 flash equals 500 hrs, 2 flashes 1000hrs

Smoke he called at like 8 tonight......he acted as if he never talked to me before!!! Lol!! The price is at 2000.00 now. He was all about 1500.00. Sombody must have fixed an idle issue he said he was having and now thinks it worth more. He lost me when he acted like he never spoke to me before.
 
ok thx... I was 'in' for $1500 and honestly it's probably still worth it at $2k also but at that price I'll hold out for more HP....... Plus WTF... talks to you at $1500 and then changes his price n wants to play games.... He lost me too there...

good lookin out tho
 
Late 90's Evinrude 150 loopers are everywhere,.........put out closer to 165 hp at prop, and are very reliable carb motors. Lots of them for sale, and easy to check the basics including compression.
