All of the boat biulders that used that Volvo engine package got shafted by Volvo who told them the engine was designed to run in a small compartment with a small amount of air going to it.
Then when the biulders all had issues Volvo would not step up to the plate as they had Promised. Everyone in the industry had issues with those engine packages.
As for World Cat they have been the most stable of all of the companies while constantly evolving to biuld a better productand with lots of satisfied customers.
As for the 33TE go run all 3 in a 4ft swell with 2ft of mixed chop then you will see why you will love the way a cat runs so well at 28knots and is so stabile trolling in that sea.
