I have the version of the 3YM30 where the heat exchanger is on the port side.
After removing the three bolts on the front face (not to mention removing the alternator), the small front plate in front of the heat exchanger element won't come out.
Can't find a way to get any purchase. Any ideas?
2007 Hull 332.

See figure 15 on page 19 of the parts catalog. I would use a wooden block and hammer on the edge of the bonnet inlet to try and break it loose.

Position wood / hit it in which direction? Sheering left to right?

Try and rotate the flange to break the seal.
Re: Heat Exchanger Challenge
If you remove the top step from the companionway you should have more room to work in there. I would use the wood with a hammer from multiple angles to try to break it loose. Possibly some penetrating oil as well.

Re: Heat Exchanger Challenge
Would you believe it self disassembled, simply leaving it on the workbench it came apart on its own, the two ends fell off.
Next up is to slide out the heat exchanger, it isn't moving.
Does the newer heat exchanger matrix on the 2007 engines slide out, like it does in the video of the older yanmar heat exchanger? There are sevearl things that do not match the helpful 109 video on youtube, including what side of the engine it is on.
