rods & regs Posted March 7, 2014 Share Posted March 7, 2014 I have a question for all you that have more knowledge than I do about this. I have a 34 foot Silverton and I ran two 36 inch bags last year and I was able to get down to the 2.5 to 2.9 sog range. I would like to get a bit slower this year so I wondering what I could expect if I ran two 42 inch bags this year or if I should just go to 48 inch?This is all new to me so I am still in the big part of my learning curve. Thanks for your help and any advice is welcome and appreciated. Link to comment Share on other sites More sharing options...
Priority1 Posted March 7, 2014 Share Posted March 7, 2014 With that size rig I'd go to the 48". A few more rpm is a good thing for oil pressure and boat control. I have been running a pair of custom made bags for years but my boat is a 22' Islander Hardtop. I'm not even sure of the diameter but I can get 1mph or less. I'd guess the diameter of mine are 30-36 inches. I do a lot of walleye trolling. The boat control is amazing. I don't use auto pilot because of the anticipation factor. I can hold a very steady course trolling into 3-4 foot seas. This is important to me when running inline boards. Link to comment Share on other sites More sharing options...

I agree a few more rpms keeps good oil pressure and would rather burn a dollar or two more gas than a motor or two. Link to comment Share on other sites More sharing options...
rods & regs Posted March 7, 2014 Author Share Posted March 7, 2014 Thanks for the response fellas. I kinda figured that the bigger bags would help more than hurt but it still gives a bit of a 'warm & fuzzy' to hear it from experience before spending the money.

1mainiac Posted March 7, 2014 Share Posted March 7, 2014 While 36in bags are likely small for your boat how big are the openings on the outlet. My son made me a adjustable bag years ago it has a second rope that when pulled closes the outlet which improves speed control. From fully open to fully close d it gave about 1 mph of speed control which on my 18ft would drop me down to under 1mph closed and around 2mph open. The reason I mention this is you may be able to modify your current bags to slow you down more. Link to comment Share on other sites More sharing options...

If it was something I could do I would consider it.Thanks Link to comment Share on other sites More sharing options...
1mainiac Posted March 8, 2014 Share Posted March 8, 2014 The bag has about 8 D rings sewn around the outlet the control rope runs thru the D rings and clips to itself so pulling on the control rope make the outlet smaller, adding more stopping power. Just like a choke collar on a dog. Link to comment Share on other sites More sharing options...
Rascal Trophy Fishing Posted March 8, 2014 Share Posted March 8, 2014 I am curious of the rpm idle speed on the Silverton. My 33' CC idles at 700-800 rpms, perfect for slow trolling, and docking. Anything 1100 or over is running too rich imho, and the carbs. should be adjusted. I have 36" sea anchors that work pretty well this way. Higher idling also wears on the trannys faster too.

Never tried it before but I know a lot of people that swear by it. Thinking it is time to give it a shot. I found a really good bag with trip lines for about $70.00 on ebay. Just for info when trolling I put the trim tabs all the way down, helps us slow down. Link to comment Share on other sites More sharing options...
CITM Posted March 11, 2014 Share Posted March 11, 2014 I run 2 (usually just 1) 36" bag on my 33 Tiara. I have a 48, works fine in bad weather but 2 would be too much. Link to comment Share on other sites More sharing options...
1HI4X Posted March 16, 2014 Share Posted March 16, 2014 How many of you are running two bags? I like the extra RPMs I get with a bag but I seem to be working the wheel much more (probably due to the drag on one side). Link to comment Share on other sites More sharing options...
fishy1 Posted March 16, 2014 Share Posted March 16, 2014 I only run 2 when needed and no steering problems but with 2 boat is alittle more fickle. Link to comment Share on other sites More sharing options...
