Tournament 190, 1986

What is the weight difference between your current engine and your anticipated new engine?

What is the Max HP on the CG capacity plate (or look in your manual... it might be there in the specs section)?

Jequimby, coincidentally there is another active thread on this site discussing the weight that various outboards add to the stern of the various GW Tournament models. Given the smaller size of the Tournament models and the already present weight of the batteries in the starboard stern area, there come a point where too much outboard weight on the stern can affect balance and performance.

If this link doesn’t work, search for the “2000 Tournament 192” topic in the “Tips, Modifications and Electronics” forum. I think you will learn a lot from the input given by various Tournament owners discussing the question you are asking here regarding the weight of various outboards. And how much may be too much on the Tournament models.

Let's start with some clarification as to what you've currently got already. Is it a 200 hp outboard? What length is the shaft on it... 20"/25"? If it is the 200 hp VMAX, per Google a 2001 Yamaha VMAX 200 hp 2 stroke motor weighs in at 453 lbs. Comparatively, a brand new Yamaha F200 VMAX weighs in at 529/567 lbs depending on if you get the 20"/25" shaft version as well as if you get mechanical or digital controls, so a difference of around 80-110 lbs more than your current outboard. Another option would be the standard Yamaha F200 which is slightly lighter at 516/525 lbs, especially if you need the 25" shaft version of the VMAX, which would be more than 100 lbs over your current setup. I imagine your current setup also has a remote oil tank with a couple gallons of 2 stroke oil in it? Most older 2 stroke boats do and have typically around 3 gallons, of which a gallon of 2 stroke oil is going to weigh in at around 8 lbs per gallon. Which, if you remove that, you'll lose 25 lbs or so of that additional 65+ lbs you'll gain with a new motor. So, a difference now of around 40 lbs on the standard Yamaha F200, which I think is completely acceptable. If for some reason there was an issue, you could always move the battery/batteries further forward to save you some weight in the stern, if the scuppers ended up lower than the waterline, etc. I don't imagine an extra 40 lbs would be the tipping point, though it's not my boat and I'm not very familiar with one. You could always put approximately 40 extra lbs of weight in the stern of your boat and see how it sits? As stated above though, the VMAX is 529/567 lbs depending on if you need the 20"/25" outboard shaft and whether you get mechanical/digital controls, of which I imagine you're going to notice an extra 100+ lbs in the stern if you did need to get the Yamaha F200 VMAX 25" at 567 lbs. Another option, if you're not 100% set on going with Yamaha would be a Mercury 200 hp FourStroke series motor, weighing in at only 475 lbs. Which is only 20 lbs more than your current outboard, and as stated above, if you remove the remote oil reservoir then you'd actually be less than your current setup. Attached is the brochure for 1986, where if you scroll down to page 21 you'll see some basic information about your boat, though I don't see the outboard shaft length listed on there. Also attached is the Mercury outboard webpage for their FourStroke series of outboards, of which Mercury/Suzuki also generally come with a 5 year warranty as opposed to Yamaha which is usually only a 3 year warranty. Good luck on your decision.
