<p>I can directly address this. I own a Tangaroa mk1 that has had several of these yamaha 9.9 high thrust outboards. The original builder supplied two extras when I purchased the boat plus the one that was on it. I bought my boat in Annapolis Maryland and brought her down the Chesapeake and the intracoastal to Palatka Fl. In the course of that trip I exceeded 11 mph several times under this power alone.

<p>I can directly address this. I own a Tangaroa mk1 that has had several of these yamaha 9.9 high thrust outboards. The original builder supplied two extras when I purchased the boat plus the one that was on it. I bought my boat in Annapolis Maryland and brought her down the Chesapeake and the intracoastal to Palatka Fl. In the course of that trip I exceeded 11 mph several times under this power alone. By GPS. One engine full throttle. I tended to run it wide open and it did not seem to care. In extremely rough weather against strong headwinds my speed was cut to 3.5 mph but in those conditions the boat was hobby horsing terribly and I had no desire to push it faster. Several times I was in rough enough conditions that we cut our speed to 4 or so mph voluntarily. Typical cruising speed in "normal" conditions was 7.5mph. Typical fuel mileage varied between 8 mpg and 10 mpg. Carefully documented in my log. Also please note that I am sure I was overloaded and suspect the entire rig weighed about 7000 on this cruise.</p>
<p>Now for another look at this. I have moved this boat several times against wind and waves with a 2 hp nissan/yamaha 2 stroke and my 12 ft portaboat which I use as dinghy. The two hp will scoot the tangaroa along just fine in a calm condition and WILL move it against a even a serious headwind. That is an empty boat. The most recent trip was extreme. Hurricane Mathew broke my mast which came down and broke the crossbeams turning my hulls on their sides and dropping the broken mast and beams in the water under the hulls. I towed this mess across the harbor over a 1/4 mile against 10-15 mph headwinds in a chop with that same two hp dink. It was extremely slow. But the 2 hp did do the job. It has a tiny little prop and it just chewed along barely moving. It was all I had and I had to get the wreck out of the water.</p>
<p>By the way the entire boat and wreckage are now at home on my acre and I am sorting out what to do with it. I had tried to sell it but had zero real interest. At this point I am glad to still own it. Love my Tangaroa. </p>
<p>Please consider your own tidal runs, currents and wind conditions but I am certain that a 9.9 Yamaha High thrust in good condition is a good match for a tangaroa size boat.

<p>Wow thanks Mike. Thatʻs pretty good performance from a 9.9 hp! </p>
<p>As a side note I decided to go ahead and build the Narai Mk IV instead of the Tangaroa. I have the plans and the Narai is what really what makes my heart go pitter patter! lol</p>
<p>Should be able to start building sometime in Dec.</p>

<p>So after a break in, at full throttle, no masts, weighing 13-14000 lbs we did 4.5 kts on just the yamaha 9.9 without lifting the other motor out of the water. </p>

<p>Mike, that would be great! I think it would be a help for others also to have a real world test on a boat as big as the T46.</p>
<p>I think that with only Yamaha offering a line of high thrust outboards and lighter, faster type boats much more common than slow displacement boats that there isn't much real world experience to compare with.</p>
<p>I think the low geared, I mean really low compared to most outboards 2.08-2.17:1 compared to the T9.9 at 2.98:1 and the big prop it can swing really…</p>

<p>I think the low geared, I mean really low compared to most outboards 2.08-2.17:1 compared to the T9.9 at 2.98:1 and the big prop it can swing really can make a difference in power/thrust for our kind of boats.</p>
<p>Your input with direct comparison between the Tohatsu & Yamaha will be most valuable and helpful.</p>
<p>Certainly looking forward to it! :-)</p>

<p>funny you just asked that. i have the tiki 46 and was torn on what to get. i was looking at the tohatsu 20 hp long shaft with the 5" extension but it's really a motor to get a very light boat up to 20 kts quickly where the T9.9 is the range of a sailboat with a huge prop and low gearing. I decided to go with one of each. If you wait for a week for me to finish the breakin i'll let you know how fast a fully loaded tiki 46 will go with just the T9.9.

<p>Yes, I agree there! I admire the "purist" ideal, but here in Finland there would be no reasonable way to have a cat the size of a Pahi 42 without decent motors. Routes through the archipeligo can twist and turn through 90 or even 180 degrees sometimes, not to mention the wind direction!! This summer we turned a corner round an island, having the wind behind us. Expected to continue to have a nice downwind run when the wind hit us in the face ;-) Would love to visit your part of the woods…</p>

<p>Hi Allen</p>
<p>I guess you buy the gear for you boat that suits the area you sail in and the type of cruising/voyaging/daysailing you do. Also the type of weather you get.</p>
<p></p>
<p>In New Zealand the weather can be changeable at times and on occasion catch you out, so we need to be prepared for all sorts.</p>

<p>yes ,the 4hp is mainly there for 'emergency' use such the wind dropping right off and a current taking me where I don't want to go.. I find that planning a trip without an end time is very important.. mostly the shit hits the fan when there is a deadline to adhere to and you've pushed to be in a place where it is not wise to be.. a couple of motors will generally pull you out but I've learned to not put myself there in the first place and if you and if you have to motor upwind in 20+ knots…</p>

<p>Steve, that's good food for thought.</p>
<p>I don't want to get in a position that I Have to use/depend on the engine to keep me off the rocks or some other situation. The engine might not start or if it's running might 'hiccup' and then I'm in a really bad situation. </p>

<p>Really prefer to use sails instead of counting on a motor. If a Yamaha T9.9 can move a Tangaroa around that's all I need. It would be used to motor a short distance when diving (free diving) spear fishing maybe motor out of a bay before raising sails with inexperienced people with me, give em time to get sails hoisted and going without having rush kind of thing.</p>
<p>I'm not quite a purest, but want to be as close to one as I can be! Lol If the wind dies down and cant get back into bay, will just go a ways offshore and heave to with sea anchor or get close enough to drop anchor and sail in later or the next day. Will have everything i need to stay onboard for however long I like pretty much. :-)</p>
<p>Not concerned or interested in motor sailing, if there's no wind as long as I'm not drifting into rocks, which I will always be sure not to put myself into that situation, I'll just hang out onboard till the picks up again. That's part of the charm and fun for me. </p>
<p>So the 4 hp can move your Tangaroa around some as needed then? </p>
