"fast start" takes too long? 1994 Evinrude 225

[Sand Bass]

During initial start up it takes a long time for "fast start" to dis-engage. I sit at the ramp several minutes waiting for motor to idle down. Motor idles at 1200 -1300 rpm for several minutes. I try not to shift into gear with motor running this fast but people are waiting on me at the ramp and I feel like a fool just sitting there waiting for rpms to go down. After motor is warm I do not have this problem. Rpms will drop to 750 about 3 or 4 seconds after starting motor. Initial start-up has always taken a little longer to idle down but now it seems to take too long??? Is this normal?? Any help or advice is greatly appreciated!

Hi Sand....<br /><br />It's either the temp sensors in the heads or the power pack is at fault. If you have an OEM service manual, it will tell you how to check the components. Or take it to your friendly neighborhood mech and tell him your problem. You are correct in not wanting to shift at the higher RPM's.

Sand Bass,In addition to OutboardJims recommendations consider replacing thermostats as they may be stuck open causing slow warm-up on initial start-up.

OB....your reply made think of a question I never give any thought to before. Would one cold head cause the quick start to linger?

Jim, Not real sure whether the quickstart gets its signal from the port bank temp sensor,or both depending on whichever one satisfies the quickstart circuit. On the fiche printout it looks like the port temp sensor has an extra wire pigtail on lead.

Wow, thanks for the fast replies! I will install new thermostats this week (already bought them). I have another thought...I drilled a 1/8" hole in the blow off valve to vent block on this motor. I think it allows some water to circulate through heads (by-passing thermostats). Lake water is cold this time of year. Could that be causing motor to warm up slowly? Thanks again!

I think cold water temps could be a factor.How cold is the water and what is the duration in seconds on initial start-up before quickstart drops out?

Thanks OB....I'll take a look tomorrow also when I get to the shop. Maybe make a friendly call to Bombardier for some guidence. I'll post ya' when I find out something. Jim

Ob/Outboard Jim, my seloc manual states that the port side temp switch operates the quickstart feature.

Guess that's the extra pigtail I saw.If that is the case and it is thermostat related the port one may be the culprit.<br />If water temps are not below the mid 50's I don't think it would delay the quickstart very long.

Ditto OB....Sand Bass, just for s**ts and giggles, before ya' change out the T-stats, put the ears on the motor or back into the lake and start up. Touch the flat spot just forward of the T-stat housing and see if there is a difference in temp after a few minutes of idle. PLEASE DO WATCH THE MOVING PARTS. <br /><br />PS...I do believe the port side will run a little cooler than the starboard side. Just the nature of the beast.

Forgot Sand Bass....if your into servicing your own mixmaster, get an OEM manual. Much more info dedicated to your engine.

Ok, I will do the temp check as recommended. Would the hole in the blow-off valve add to the slow warm-up process? Does it allow a small stream of water to circulate through heads before thermostats open? Port side temp sensor is closest to the blowoff valve and hose connects right there at the sensor? Maybe that is why Dhadley always recommends drilling into the block and installing a second overboard indicator to vent block? Does this make sense?? Water temp here should be low to mid 50's.

The flow through the extra tell tale hole shouldn't make a difference. As for exactly where to put the extra hole can be a debatable issue. Main thing is to keep the block vented and full.

The Quick Start sensor located port cylinder, white/black wire. Switch closes 96+-3 degrees F, and releases Quick Start. Switch opens 89+-3 degrees F and engages Quick Start. You can verify power pack working by disconnecting the white/black wire. Disconnected the white/black, timing should be close to TDC, with the white/black connected the timming should shift to left of about 1 inch. Engine temp has to be over 96 degrees F and rpms about 900.

I cheated and used the manual.
