Alternative position for outboard motors? - Wharram Builders and Friends2024-03-29T06:01:52Zhttps://wharrambuilders.ning.com/forum/topics/alternative-position-for-outboard-motors?commentId=2195841%3AComment%3A139548&feed=yes&xn_auth=noThank you Robert.

<p>Thank you Robert. Yes you would be right. As I will be running two outboards which will be fixed, they will not turn, I will be relying on the forward movement of the boat and its own rudders, together with the ability of powering one motor forward and even reversing the second for tight manuevability in confined spaces. As I have marginally lengthened the beams I have enough space to site the motors in a central position between the command pod and the hulls.</p>

<p>The only advantage in having the engine further aft is if you have a single engine as then the angled thrust is more effective for manoeuvring as in effect the point of leverage is further back (I discovered this when I rebuilt the centre of my Hinemoa and moved the engine forward, it cavitated less but my turning circle increased despite the engine being able to be rotated just as much.<br></br> <br></br> <cite>Charlie said:…</cite></p>

<p>Steve, I admire your attitude and purity, but having no engines would not work for me. Here in the Baltic, and particularly the Finnish archipelego, it would be very very difficult to get into any harbour and basically would confine you to only sailing on the open sea. All the costal routes (marked channels) are very rocky and often dog-leg, if not turn 180 degrees sometimes. Trying to tack along that type of route with a big Wharram is "interesting" - & slow! But great if you can do…</p>

<p>Thank you all for your comments and suggestions, together with photos. Looks like I will run with two outboard pods mounted amidships alongside the command pod and forward of the cockpit for better weight distribution and manuvability. If anyone has further photos of outboard pods that would help me design, please post them. This would be appreciated........thanks again.</p>

<p>I took my motors off.. 2X 9.9 yamahas... My boat (Tangaroa mk IV ) sails so much better.. I have a 4hp for if there is absolutely no wind.. I have done around 1000 nm around the north queensland coast and islands since I removed them and I don't miss them at all. If you have to sail everywhere then you learn how to sail your boat well . And Wharrams do sail surprisingly well.</p>

<p>Our Pahi 42 has two engines mounted in pods, very similar to the above picture. Our engines are 9,9s. I think it could work to move the pods further forward, but easy access to the motors is essential and you need to have clearance for the top part of the motor, so you would use space from inside a cockpit locker to achieve this. Our pods swing from a point on the front edge of the cockpit, so just behind the 3rd beam. The pods I built are a simple V-shape but I have heard that they should…</p>

Our pods swing from a point on the front edge of the cockpit, so just behind the 3rd beam. The pods I built are a simple V-shape but I have heard that they should float on the water for 1m or so in front of the engine, a bit like a mini-optimist dinghy. If you do that, there will be less clearance when in the raised position.</p>

<p>The Tiki 38s have their motors mounted fwd of the pod under the cockpit settees. We have built sleds similar to the T38s that hinged down from the cockpit for a pair of outboards. I find further fwd desirable as the weight is more central and the motors will ventilate less.</p>
<p>Just saw above photo,,, very similar to what we did for the sleds. Quite different on deck arrangement.</p>

<p>I saw this boat in Tonga in 2011 and Inga I think was very happy with his set up. Would recommend 4 stroke as opposed to 2 stroke. Remember 2 stroke leave behind an oil slick on surface of the water. Not good for our dolphin and whale friends:) Much quieter too.</p>

<p>Hi Graham,</p>
<p>I have seen a Pahi 42 with 2 15HP fourstroke motors, and it worked well. See below picture of Mahuini.</p>
