What size gas springs for a 220 ssi engine and ski compartments?

18 posts in this topic

I just bought a used 2004 Chaparral 220 SSi. The spring lift gas springs under both the engine compartment and the ski compartment do not hold the compartments up on their own. The first question I have is, are they supposed to? I assume so, but I didn't know if perhaps they were only meant to lower it slowly rather than actually holding them up.

Assuming that they are supposed to hold them up on their own, what part numbers are the "factory-specified" parts? My ski compartment has a spring lift SL33-40-1. My engine compartment has two SL34-120-1, one SL34-60-1, and one SL34-80-1. Are those the factory parts? If they are, should I simply replace them, or should I upsize them assuming that my engine compartment weighs more now due to water or dirt?

Any help would be much appreciated. I don't want my engine compartment to open up on its own if I upsize the springs too much!

I would think that if I buy ones with too high of a pressure rating, the engine compartment may even lift up on its own.

Four struts to hold up the motor box? Should be two only.

Yes, there are definitely four there. And they still don't hold it up! Only the home made wooden stick does that. :slap:

Go to the "Chaparral Boats" web site, and at the top of the page you will see "Customert Support"; On that page you will see "Parts Lists". They list your boat parts and have very good photos of everything.

Hope this helps.

My 220 also has 2 struts. They do hold the engine compartment open, but it's marginal. Seems to be fairly common with boat builders to use marginal sized struts in these applications.

If 4 struts are not holding it up, maybe it has gained some water weight. Check the mounting holes for the sunpad, as they can let water wick into the core material. Or could be 4 worn out struts. Still not sure why you would have four...

Same here. 2 struts total, but they *barely* hold the engine compartment open.

I just replaced the struts on my 2001 216SSi and I was able to find EXACT replacements at iBoat for ~$15each. just enter the SL part number.

I have a friend with a 2006 220 and he only has 2x gas lifts. Would be interesting to see picture of 4x??

*NOTE the engine cover / sunpad is HEAVY... I used 2x 2x4s to hold up the sunpad while I replaced the gas lift.

Here's a photo of my 4 gas springs in my '04 Chap 220 SSi engine compartment. Merc 5.7engine. It looks different from the way it looks in their manual, but the engine in the manual is a Volvo. Not sure if this was the standard method for the Merc engine or not. Interested in hearing from others with '04 220 SSi Merc 5.7

Take one off and head to an auto parts store.... I bet someone like NAPA can match it .

That's not what mine looks like. And not what my 2002 220SSi looked like either. Maybe someone added two extra struts, as it was not staying up? I still think you have water in the motor box, making it too heavy for the struts.

Is the oil filter from 5/08?

Does your 220 SSi have 'Sport' seating with 2 buckets and a rear solid bench with no walk-thru, or does it have 2 buckets with the walk-thru and an 'L' shaped rear bench?

Yes, the filer is marked 5/08 and says 150 hours on it. Time for a change!

Also, the seating is the L-shaped rear seats with walk through. We also have cushions that can be put in the walkthrough to make the seating go all the way across.

What weight rating are the struts? I can check to see what mine are.

I have a 09 216ssi that was bought new in '10. I went through 2 set already. Luckily covered by warranty. Betting that mine are undersized
