Got kicker! Now need bracket and fuel advice...

I snapped up a 5hp 4-stroke Honda ('85 but in great shape). I'm going to use it on my I/O boat---a Glastron '69 with an impressively curvy transom (not just a regular curve, but swoopy). Here's my plan; all advice is welcome. <br /><br />I think I'll have to modify a stock bracket to fit, perhaps with a rubber spacer or two. I'll mount it very near one side, so that it won't have to sit very low to get the prop below the hull. I'll route a fuel hose out the transom (not sure about this---perhaps through the deck near the transom?), high enough not to have to worry about leaks, but sealed up anyway. I'll put a T in the I/O fuel line between the water separator filter and the fuel pump, and attach a fitting there for the outboard fuel line. I'll keep the priming bulb outside the engine compartment.<br /><br />Question: how high should I ensure that I can raise the outboard? I'm not going to keep the boat docked, so it's a question of being underway---is it enough to be able to raise it so the prop's not under the hull, or should I be able to get the prop out of the water? I'm thinking the former, since I'll use the kicker for most low-speed stuff, and I won't mind a little drag from it if I happen to use the I/O at low speed---and at planing speed the kicker will be out of the water anyway.<br /><br />THanks for any tips!

Hey Marc, I would not tap into the existing line at all. It seems to me that you will have a conflict between the two fuel pumps.<br />I would use a separate tank.<br /><br />How are you going to steer this motor? I read about a guy somewhere that just left his motor in a fixed position and did the steering with the outdrive, when he needed a little extra power he just fired up the big motor, even while the little guy was still running. seems like a good idea to me.

Re: Got kicker! Now need bracket and fuel advice...

Sorry for the delay in replying, but I just spent a wonderful long weekend on Lake Sonoma (CA). I stalled out just before picking up our guests :-(, but the Mercruiser behaved itself all weekend after I cleaned the points. <br /><br />Steering. I think I'll use that idea of steering with the outdrive when trolling or going a long way. Otherwise I'll sit on the back deck---not much fun, but not a common scenario, since I'll do that only when the I/O isn't working.<br /><br />Still hoping for bracket ideas/tips... !<br /><br />Mark

Re: Got kicker! Now need bracket and fuel advice...

I think that your idea is good as far as how high the motor has to be. Just make sure it is high enough to clear the water while on plane. As for the bracket itself its hard to picture what you are up against without seeing your particular transom. It shouldnt take much to support this motor, just make sure that you run your bolts all the way through the transom and use large washers on the inside.<br />Glad you had a good weekend, sounds fun!

Just a afterthought.. have you seen the brackets that pivot up and down? or is that what you are talking about. Also your previous gas line idea could work if you installed a 3-way valve to isolate the main motor fuel pump, but still not a good idea IMHO. If you forget to switch it you will suck the dirt and eventually air from your main motor plus you are adding another possible point of gas leakage in this enclosed area. Also I would keep the Honda high enough to clear even while on a semi-plane(bow high).

Re: Got kicker! Now need bracket and fuel advice...

Thanks! I think one of those raising/lowering spring-loaded brackets would probably be the best idea.<br /><br />I'm still wondering about the fuel thing. What do people do who have dual outboards---do they use separate fuel tanks? I see your point about one motor pulling fuel from the other, but would anti-siphon valves prevent that?

I am sure that many would argue the one anti-siphon valve located at the fuel tank is almost one too many. They are restrictive and prone to fail. Good Luck

Fuel to Kicker<br /><br />As installed on aluminum jetboats used for river running. They will run either a "T" into the line before the main fuel pump, or on later fuel injected models with high pressure pumps intank they run a seperate supply line and terminate it to a standard 3/8 angle barbed to bulkhead fitting then on the exterior into the bulkhead fitting goes a suzuki/ and perhaps Yamaha quick connector, These have a ball check that seals off the fitting if disconnected.<br /><br />

Yepblaze and Evin300, you guys are wonderful sources of help and information. Thanks! <br /><br />Hey Yep, I take it the jet boat guys don't put in any kind of device to keep the kicker from sucking gas and air back out of the main engine or vice versa? I like the idea of the self-seal fitting outside the transom.<br /><br />Thanks for the picture, too.

Re: Got kicker! Now need bracket and fuel advice...

If the kicker and the main engine pump are drawing from the main feed there really shouldn't be a problem. Seeing if both are connected and seeing as they both have fuel pumps with one way check valves in them (thats how they work) One can't pull back from the other only from the tank. Those fittings I was reffering to (Suzuki/Chrysler type as I've seen them labled at Wallmart)have a ball inside of them that seals off the fitting to pressure and some vaceyuumeee. (how much vacyyyyummeee I'm not sure of)But at any rate you could get another female fitting and put a plug in it to attach to the bulkhead fitting if you decide to remove the kicker. Just for good mesure. Basically from the male on the bulkhead, you attach a female to a hose then the primer bulb, then you honda fitting. Once connected up it should be fine "T"'ed into the main engine feed. Just have to make sure that all is sound with no air leaks as the main engine would then pull air from your poor connection rather that gas up from the tank.

Sure you're spelling vaghkyoum right? :)<br /><br />Knowing nothing about fuel pumps other than that they pump, I kind of suspected that they wouldn't allow siphoning. Thanks for confirming this.<br /><br />Your fuel plan sounds right to me. Worth a try, in any case. I'll keep an eye on ebay for brackets, and meanwhile fix up the fuel set-up.<br /><br />Thanks lots. Hope to see you on the Delta one of these days! (I really liked launching at New Hope Landing, which I believe you recommended in an email.)
