Compression test (2000 evinrude 115 FIHCT)

Recommended Posts

Hi, im planning on getting a boat with a 2000 rude 115 on it and before i close the deal i wanna do a compression test on it. Does anyone know what that psi each cylinder should be for this motor or anything close to this? Thanks in advance!

Make it easy, take it to a tech that works on Evinrude. He will do the check and look for other things as well. I bought a '99 Nitro with a 200 Merc and the seller paid for the mechanic. I suggested it, he bit....done deal. But to answer your question, it is my understanding that the # should be above 100 and all very close together. Good luck!

All cylinders should be over 100lbs and have no more than a 10% difference in any of the cylinders.

Agreed. Although knowing what the presure should be is better. The 10% rule is very effective at noticing problems. The chance of all cyclinders having the same amount of damage is nil. Usually one cylinder gets damaged at a time. It will stick out like a sore thumb in a comparison compression test.

If one cylinder has 10% lower compression or worse it is usually representative of a scared cylinder wall, broken piston ring, blown head gasket, or other similar damage. There is never an easy fix.

X2, and it usually will run you 500-600 a hole to repair it. Get a qualified mechanic to check it out. It is money well spent. Good luck.

we closed the deal on the boat. My dad brought all the equipment to do the compression test but the plugs were too deep down. We took a test drive and the motor seemed pretty strong.

Its not much of a bass boat but its pretty nice though, 17ft mako 171 with a t top and full electronics( stereo plate needs to be replaced). Gotta start saving up for salt water gear :'(. Ill get pics up tommarow! Its my first boat too ;D

I never worked on a V4 but my 1999 V-6 Ficht runs 128 pounds, I would suspect the V-4 is just about the same.

Now I'm going to tell you the rest of the story. The early fichts (pre 2002) were plagued with problems. The early V-4s were the black sheep of the lot. Even the factory tech reps hated them. The V-6's had problems but most were ECU related and with major upgrade, most of those problems go away. This ECU upgrade is about $800 and is done by an aftermarket source, not BRP.

Another problem is they are very sensitive to old gas. Let one sit for three or four months and you may have problems. I pump out my gas tank and connect a two gallon tank (which I only add a gallon at the time) to mine when not in use and add two ounces of SeaFoam per gallon. I crank it a let it idle about 15 - 20 minutes every couple of weeks. Just letting them sit and you may find yourself needing a piston or two the next time you take it down the lake.

Whelp.......I was looking at a nice used Ranger with a 1999 Ficht.

I've had an Evinrude tech tell me to stay away from ANY Ficht older than a 2000.

Your info just about sealed it's fate for me. No sale.....I don't want those problems.
