Remote to Tiller

[Dunk50]

I have a nice 16' deep v Sylvan I am happy with.It is rated for 60hp tiller. On the other hand the 35 doesn't get it. I cannot find any selection or basically any used 60HP tllers. I have changed some older 30 and 35 back and fourth but how available are the tiller handles for the 60's and is there much else to change. <br /> 2nd question is If I go through the trouble of putting a console in, can I legally get my HP raised to open up more options to 70 or 75. It is an older ealry 80's heavy solid boat. I fish a long stretch of river and the trip is just to long time wise. Any help would be appreciated. South Bend Indiana

Re: Remote to Tiller

Trying to run your boat with a 60HP tiller will be a REAL handful. Personally, I wouldn't use a tiller on any thing over a 25HP. If , big if, you can find one for your motor, the swap isn't all that hard. Think you would be better off buying or fabricating a console for your planned bigger motor. Words of advice though( as I too was contemplateing switching from a tiller to console). Unless you REALLY love your boat, I would sell it "as is" and buy something already setup. You will have alot of time and $ in doing a swap. As far as the rating goes??? Normally, console boats can hold a bigger HP than tillers.

Re: Remote to Tiller

You should be able to find a tiller for many outboards up to 90 hp. Most under this hp are remote/tiller convertable, and the conversion parts (tiller) should be available through your dealer. Most tillers come with cables and it's a simple change over. If the outboard doesn't have the optional pull rope you may need to relocate the key switch. Try the commercial models like the Enduro's, etc.<br /><br />I see no problem with running a tiller over 25 hp . Yamaha makes the F115 in a tiller model. I've operated many larger tillers and find them convenient and safe.<br /><br />"Legally" changing the HP rating is a gray area. I've never seen a Coast Guard citation for exceeding the manufacturer's certification, but I suppose it could happen. Usually the operator would get cited for wreckless/dangerous operation instead. Boat manufacturers are not required to certify the boat at its maximum hp rating, and may rate the boat at less hp than the maximum allowable. Also the authorities have no way of knowing exactly how much hp you have.<br /><br />Without changing the little yellow certification plate, you could use the Coast Guard's own federal requirements to prove your hp increase is legal. Do this.....<br /><br />Calculate your "factor" by multiplying the length of your boat (ft) X the maximum transom width (ft). Transom width is the broadest beam in the aftermost quarter length of the boat. The following is only true if that "factor" exceeds 52.5. <br /><br />For boat with no remote steering (tiller) or less than 20" transom height....<br /><br />Flat bottom hard chine: HP = (.5 X "factor") -15.<br /><br />Other boats (this should be you): HP = (.8 X "factor") -25.<br /><br />For boat with remote steering and at least 20" transom height.....<br /><br />HP = (2 X "factor") - 90.<br /><br />You can round up to nearest multiple of 5 hp.<br /><br />Since your boat is rated for 60 hp as a tiller, and you say it is a "V" hull.....<br /><br />60 HP = (.8 X "factor") - 25. This means your "factor" is 106.25.<br /><br />Now, using the tiller formula......<br /><br />HP = (2 X 106.25) - 90. HP = 122.5 HP or 125 HP (rounded up).<br /><br />Or.....assuming (?) your boat is 16 feet long X 6 feet wide (72"), your "factor" would be 16 X 6 = 96.<br /><br />Now, using the tiller formula......<br /><br />HP = (2 X 96) - 90. HP = 102 HP or 105 HP (rounded up).<br /><br />So a 60 HP tiller would safely equate to about a 100 HP console.....for your boat. Using these calculations the Coast Guard would have a hard time ticketing you for a 100 hp outboard....with a console.<br /><br />Hope this helps.

Re: Remote to Tiller

I found the Coast Guard formula. Actually my boat is 16’3” with a 72” transom and is 26” deep transom. What I do not understand is that a lot of the Coast Guard and other sites state that the HP rating is also for weight and level flotation. I too figured the formula and with console came up at 115HP or so. Without is more than 60HP with tiller but I forgot the actual figures. I’m not looking at 115 but I would like some options other than the 60HP tiller. It can’t be that difficult to install a console. I mean if I can build a house I can build a console. Anything else you can tell me please do. I have not done it before but I will in the next few weeks. What else are winters for??

Re: Remote to Tiller

You can buy ready to install complete consoles through places like Overtons, etc. $200-$300.<br /><br />HP ratings, weight capacity, and persons capacity are all different things, all figured seperately. All three must be permanently displayed on the boat.<br /><br />Persons capacity (outboard boats): Must not exceed the lesser of the maximum weight capacity for the boat minus the motor and control weight, battery weight (dry), and full portable fuel tank weight.<br /><br />Or..<br /><br />For boats with a maximum persons capacity less than 550 pounds, the boat must be float tested. Float the boat with all accessories. Add (in normal operating positions) the dry motor, control weight, battery weight, and full fuel. Load boat with weights (according to instructions) until the boat assumes the maximum list or trim, or both without water coming aboard. <br />Compute the maximum persons capacity in pounds using the formula A/0.6 where A = total of weights added (per above).<br /><br />The persons capacity in whole numbers of persons must not exceed the value obtained by adding 32 lbs to the lesser of the values above divided by 141 and rounding off to the nearest whole number. If any fraction is less than one half, round down. If fraction is equal or greater than one half round up to next higher whole number.<br /><br />Weight Capacity (outboard boats):<br /><br />The maximum weight capacity must be a number that does not exceed one-fifth of the difference between its maximum displacement and boat weight.<br /><br />Maximum displacement is the weight of the volume of water displaced by the boat at its maximum level immersion in calm water without water coming aboard except for water coming through one opening in the motor well with its greatest dimension not over 3 inches. A boat is "level" when it is transversely level and when either of two conditions are met: the forward point where the sheer intersects the vertical boundary of the transom are equidistant above the water surface or are equidistant below the water surface. Or the most forward point of the boat is level with or above the lowest point of water ingress.<br /><br />"Boat Weight" is a combination of hull weight, deck and superstructure weight, weight of permanent appurtenances, and weight of full permanent fuel tanks.<br /><br />We already discussed HP rating. <br /><br />I've designed and built a few boats using these theories. They work.

Re: Remote to Tiller

Thanks all for your input. I ended up going to Lodi Wisconsin and buying a 1993 Evinrude 60HP tiller. It has tilt and trim and 15 degree prop. Took it to the river and it is perfect. I'm 56 years old and don't play around (read drive stupid) but when I head up river I like to get there before the fish die of old age. the 60 pushes me right around 38mph using a gps for speed. It has the TNT whitch on the motor housing and that is very awkward and dangerous to try and trim it under full throttle. I rigged up a second switch that I can use with my right hand while steering with my left. Kind of like running a snowplow. Love it alot. Now about price. Couldn't find but one motor within 3 to 400 miles. I paid $2245. It appears and runs like new. ?????

Re: Remote to Tiller

Glad you have solved your problem and like your new setup. You are right about larger hp tiller motors being hard to find. I hope you enjoyed your brief visit to WI.

Re: Remote to Tiller

I did and the Marina was great. Very professional and helpful. If anyone gets around Lodi Wisc. don't hesitate to go to Don's Marine. They even have a nice web sight.
